Since you are using perl, it may be more useful to start from something
like mail/p5-MIME-Lite instead of rolling your own.

Since the introduction of Thunderbird 3.0 and Firefox 3.6 I see
spontanous crashes/coredumps of both thunderbird and firefox. Interingly
Firefox 3.5.X works well on he same platform.
The platform is a FreeBSD 8.0-STABLE/amd64 (r205536: Tue Mar 23 22:19:04
CET 2010), SMP box with 8GB of RAM, QuadCore Intel Q6600 on a P35-based
motherboard.
Thunderbird 3 crashes rarely compared to Firefox 3. The longer the
application thunderbird runs, the higher the likelyhood the app crashes
and vanishes. Sometimes this happens immediately after starting
thunderbird, sometimes it takes its few minutes or half an hour.
Firefox 3 is sensitive to its pull-down menus or requester showing up in
some situations. I can provoke a crash by clicking onto a pull-down-menu
in firefox 3, it immediately dumps a core.
Well, I wouldn't write s cross-posting if I would be sure this behaviour
is due to some oddities in my installation, but since this odd behaviour
occured both on Firefox 3.6 and Thunderbird 3 in several situations and
with several tries to get a workaround, I feel desperately lost.
What I did so far:
- Recompiling EVERY port on my box (four times in a row to make sure
everything is right, its a pain with nearly 950 ports).
- Deinstalling both Firefox 3 and Thunderbird 3 and installing the
binary packages from FreeBSD.ORG
I have a private UP box, running the same OS FreeBSD 8.0-STABLE/amd64 on
a single core Athlon 3500+ with only 2GB of RAM. There I use both
Thunderbird 3.0.3 and Firefox 3.6.2 without any problem.
I suspect the X11 server or some part of the accelerator stuff
triggering the crashes. On the both machines,
WITHOUT_NOUVEAU = YES
is defined. On the UP box at home, I utilise a HD4830 graphics
accelerator with DR enabled. The lab's box have had
both HD4670 and now HD4770 accelerators, both do not work properly with
the state-of-the-art drivers supported by the official pots collection.
HD4670 never got to work since the new RadeonHD driver 1.3 was
introduced (prior to that it worked), the new HD4770 works with
explicitely disabling DRI and crashes whenever I leave a session (quit
windowmaker). Well, this is another story, but I suspect the Radeon
driver infrastructure causing the problems - but I'm not sure.
I use perl-threaded 5.10, but I guess this is not a problem since the
problems occur whether I have threaded perl or not.
As I said, I feel like a dead man in the water ...

Oliver

If you suspect the graphics card's driver is at fault then I would try
linux-opera or even linux-firefox and see whether it also dies when you
use a drop-down menu.
Another possibility would be to set hw.physmem to say 3G or 4G in
loader.conf and see whether that affects thunderbird/firefox. Who
knows, there may some weird problem caused by all that memory? That
would a fairly quick and cheap way to test this.

Message-ID:
<cf9b1ee01003240918g3a7...@mail.gmail.com>

Hello
I am having a slight issue (and judging by Google results, similar
issues have been seen by other FreeBSD and Solaris/OpenSolaris users)
with writes choking the read IO. The issue I am having is described
pretty well here:
http://opensolaris.org/jive/thread.jspa?threadID=106453 It seems that
under heavy write load, ZFS likes to aggregate a really huge amount of
data before actually writing it to disks, resulting in sudden 10+
second stalls where it frantically tries to commit everything,
completely choking read IO in the process and sometimes even the
network (with a large enough write to a mirror pool using DD, I can
cause my SSH sessions to drop dead, without actually running out of
RAM. As soon as the data is committed, I can reconnect back).
Beyond the issue of system interactivity (or rather, the
near-disappearance thereof) during these enormous flushes, this kind
of pattern seems really ineffective from the CPU utilization point of
view. Instead of a relatively stable and consistent flow of reads and
writes, allowing the CPU to be utilized as much as possible, when the
system is committing the data the CPU basically stays IDLE for 10+
seconds (or as long as the flush takes) and the process of committing
unwritten data to the pool seemingly completely trounces the priority
of any read operations.
Has anyone done any extensive testing of the effects of tuning
vfs.zfs.vdev.max_pending on this issue? Is there some universally
recommended value beyond the default 35? Anything else I should be
looking at?
- Sincerely,
Dan Naumov

It is always good to make a 'clean install' but upgrading from some 6x
to 7.3 should be reasonably doable. (Note, you failed to put all of
your information in the body of the message. It is not helpful to
put relevant information only in the subject line)

The vdev.max_pending value is primarily used to tune for SAN/HW-RAID
LUNs and is used to dial down LUN service time (svc_t) values by
limiting the number of pending requests. It is not terribly useful
for decreasing stalls due to zfs writes. In order to reduce the
impact of zfs writes, you want to limit the maximum size of a zfs
transaction group (TXG). I don't know what the FreeBSD tunable is for
this, but under Solaris it is zfs:zfs_write_limit_override.
On a large-memory system, a properly working zfs should not saturate
the write channel for more than 5 seconds. Zfs tries to learn the
write bandwidth so that it can tune the TXG size up to 5 seconds (max)
worth of writes. If you have both large memory and fast storage,
quite a huge amount of data can be written in 5 seconds. On my
Solaris system, I found that zfs was quite accurate with its rate
estimation, but it resulted in four gigabytes of data being written
per TXG.

Problem solved. Hopefully the answer might be of use to others, as it
doesn't seem too uncommon a situation.
I'm using a serial console. By default, FreeBSD 7 had both uart and sio
compiled into the kernel, but device.hints gave configuration info for
sio only. FreeBSD 8 removed sio support completely, leaving uart only.
As device.hints contains nothing about uart, there was no serial device
available for the console. The system was infact starting to boot quite
happily, albeit without any console output, but wasn't completeing due
to geom_mirror not having been loaded. The solution was simply to
change hint.sio.[01].* to hint.uart.[01].* in device.hints, and to
change ttyd0 to ttyu0 in /etc/ttys.

There isn't a sysctl for it by default, but the following patch will enable
a vfs.zfs.write_limit_override sysctl:

I had similar problems on a 32GB Solaris server at work. Note that with
compression enabled, the entire system pauses while it compresses the
outgoing block of data. It's just a fraction of a second, but long enough
for end-users to complain about bad performance in X sessions. I had to
throttle back to a 256MB write limit size to make the stuttering go away
completely. It didn't affect write throughput much at all.

Had I read /usr/src/UPDATING more carefully however, I might have spotted,
20080713:
The sio(4) driver has been removed from the i386 and amd64
kernel configuration files. This means uart(4) is now the
default serial port driver on those platforms as well.
To prevent collisions with the sio(4) driver, the uart(4) driver
uses different names for its device nodes. This means the
onboard serial port will now most likely be called "ttyu0"
instead of "ttyd0". You may need to reconfigure applications to
use the new device names.
When using the serial port as a boot console, be sure to update
/boot/device.hints and /etc/ttys before booting the new kernel.
If you forget to do so, you can still manually specify the hints
at the loader prompt:
set hint.uart.0.at="isa"
set hint.uart.0.port="0x3F8"
set hint.uart.0.flags="0x10"
set hint.uart.0.irq="4"
boot -s
which is probably why noone else has suffered from this problem.

Hi all,
i'm still new on freebsd, please help me.
i had installed pure-ftpd. it is working with the anonymous login.
i'd like to make it non anonymous login, so only authenticated user can

here what i did :
# Don't allow authenticated users - have a public anonymous FTP only.
AnonymousOnly no
# Disallow anonymous connections. Only allow authenticated users.
NoAnonymous yes
i think with this i had set no naonymous login (that what i got after
reading the manual)
but this is appear:
220-You are user number 1 of 50 allowed.
220-Local time is now 01:53. Server port: 21.
220-*Only anonymous FTP is allowed here* (why this could happen? what is
wrong?)
220-IPv6 connections are also welcome on this server.
220 You will be disconnected after 15 minutes of inactivity.

i had made the newftp user with password, but it still can.t login.
anyone can help me? Thanks before

Apparently this was a kernel thread priority problem in Solaris. It
is apparently fixed in recent versions of OpenSolaris. The fix
required adding a scheduling class which allowed the kernel thread
doing the compression to be less than the priority of normal user
processes (such as the X11 server).

If you want 100% of the drives you could have a pool per drive. Its not as
nice as one big pool, but its less risky than one big raid0

Greetings - (not a draft notice)
First thanks to those who responded to my previous question.
Next...
I was attempting to install 8.0 amd64 w/ZFS. I used instructions from the wiki
and when I had trouble, I decided to beat a strategic retreat and just do a
"vanilla" install. Problem was that either fdisk didn't recognize the mbr
after all the 'gpart create'-ing or simply couldn't start newfs. (Something
about not being able to find an initial inode.) I figured 'gpart destroy ad0'
might fix things but no such luck. fdisk -I ad0 also errors out saying "unable
to locate class".
Does anyone know of a simple (brute force?) way to restore simple. standard
MBRs without having to resort to a hex editor? (I will if I have to, but I'd
rather not.)
Thanks for any assistance...
IHN,
Gene

Mostly a wild guess, but can you test if this patch will help with
choking your network and ssh:

?
You can then fiddle with the vfs.zfs.zio_worker_threads_count loader
tunable to see if it helps more.

This will wipe the MBR: dd if=/dev/zero of=/dev/sdb bs=446 count=1
replace of=/dev/sdb without whatever /dev/sd? you need.

The last time this topic came up IMO there was quite some
interest in getting this running but the showstopper was that
cperciva@ said that a requirement for any platform supported
by freebsd-update(8) would be that the build server is able
to run buildworld in 1 hour at most (unfortunately I currently
just can't find that email). My 4x1.5GHz V440 I originally
intended for this purpose unfortunately still takes 72 minutes
last time I checked. I suspect a 8x1.2GHz V880 would be able
to meet this requirement but I simply can't afford the housing
for such a beast.
Ken, did the V880s at your university become available as
intended some time ago?

proceed with the installation"
To: ques...@freebsd.org
Message-ID: <4BAAB9FD...@cam.ac.uk>
Content-Type: text/plain; charset=ISO-8859-1
Hello,
Having run into various problems trying to upgrade from 7.2 to 8.0, I'm
instead trying to perform a clean install using sysintall.
I've downloaded 8.0-RELEASE-amd64-memstick.img, modifed it to use a
serial console and flashed it to a USB drive. This boots quite happily,
and presents me with the sysintall screen.
I'm intending to install to a pair of drives, mirrored with gmirror and
partitioned with GPT. I therefore immediately drop into the fixit
shell, create the mirror, partition it, and mount the new partitions
under /newroot/, /newroot/usr etc. I then exit back to sysinstall,
select custom install, point install root to /newroot and choose
distribution, media. On selecting commit, sysinstall immediately
presents the message "You need to assign disk labels before you can
proceed with the installation", and won't proceed.
It seems this only happens when sysinstall is running in single user
mode. I have manged to make some progress with tricking sysintall into
getting past this message. If I run sysinstall within the fixit shell
(rather than exiting), I get a new instance of sysinstall with a pid
other than 1. Symlinking /usr/bin to /stand, seems to provide most of
the binaries it needs, and it proceeeds part of the way through
installing the system before getting stuck on the documentation.
I avoided this problem when installing 7.2 by creating an mfsbsd image,
booting that, and then running sysinstall from there, but I'd rather not
have the hassle of doing this for every future release. Moreover,
creating an mfsbsd image may not even be an option in the event of a
diasaster.
Is anyone aware of any way of installing using sysintall from the
standard FreeBSD media, but without using sysintall to partition and
label the target disks?
Kind regards,
Christopher Key

Hi;
I followed the instructions from
http://www.freebsd.org/doc/en/articles/custom-gcc/article.html
to see if I can achieve some performance gain (8-STABLE r205630 amd64) and
also get a more modern instruction set for my Phenom II (amdfam10), so I've
done the following config settings:
make.conf
.if !empty(.CURDIR:M/usr/ports/*) && exists(/usr/local/bin/gcc43)
CC=/usr/local/bin/gcc43
CXX=/usr/local/bin/g++43
CPP=/usr/local/bin/cpp43
CFLAGS+=-mssse3
CPUTYPE=amdfam10
.endif
libmap.conf
libgcc_s.so.1 gcc43/libgcc_s.so.1
libgomp.so.1 gcc43/libgomp.so.1
libobjc.so.3 gcc43/libobjc.so.2
libssp.so.0 gcc43/libssp.so.0
libstdc++.so.6 gcc43/libstdc++.so.6
buildworld goes on normally it seems, but when I tried to build the kernel,
the first stop came from the option used by the kernel build "-fformat-
extensions", which is not accepted by gcc43, so I took it out of
/usr/src/sys/conf/kern.mk, the ONLY place I found it.
It seemed to solve the problem until gcc43 stopped because of the "-Werror"
option, which is all over the place!. Funny that gcc42 (used by default)
doesn't stop because of this option.
Anyway,my question boils down to: Is there a way to build the kernel with
gcc43, with minimal tweaking? Am i attempting something out of my league?
Thanks,

It seems the reboot of your Linksys switch helped some how.
Before portupgrading randomly this or that application, you should try
to understand what is going wrong.
Upgrade of DNS should go easily, but when you start upgrading web or
mail, you are talking about tens or hunderds of applications, you are
very likely something goes wrong and you break a system that was
working before.
When you say you could not "get" to ethic, what do you mean?
- Cannot ping?
- Cannot ssh?
- Cannot telnet port 22, 25, 80?
- Cannot traceroute (if your station and the server are on different
LAN)?
- Cannot ping another machine on your LAN?
- Are you sure it was not your desktop that was faulty?
- Etc.
You should make a diagnostic before trying to apply any solution.
As the reboot of thw switch did it, to me it looks like a network
issue: bad switch, bad cable, some highly infected machine on your LAN
that is stressing the swtich, rather than a server/service issue.
Good luck,
Olivier

Hi,
My workstation runs FreeBSD 8.0-STABLE amd64. I have Xorg 1.6.5 and an nVidia GeForce 5200 dual head video card.
Currently the first head of the card is operating well using the "nv" driver. I tried to compile the nvidia-driver port, but it tells me that I need nvidia-driver-173 because the 5200 chipset isn't supported by the current driver. When I go to compile nvidia-driver-173 it tells me that it is not supported under the amd64 architecture. I can't switch to an i386 kernel because I need the amd64 architecture to take advantage of all my RAM and also because I am using ZFS on this workstation, which more or less requires the amd64 architecture.
So, I have two questions:
1. Is there any way to get the nvidia-driver-173 port to work with my amd64 OS?
2. Is there any way to get the second head of the 5200 video card to work using the nv driver? I tried adding a second device section to xorg.conf but the system errors out telling me that it tried to use conflicting hardware. I've attached both my xorg.conf and my Xorg.0.log file to this message.
Or am I stuck buying a newer card?

Hi guy's,
I downloaded the DVD version freeBSD version 8 and went to unpack it
and got these messages from winrar.
! D:\FreeBSD\8.0-RELEASE-i386-dvd1.iso.gz: Unexpected end of archive
! D:\FreeBSD\8.0-RELEASE-i386-dvd1.iso.gz: CRC failed in
8.0-RELEASE-i386-dvd1.iso. The file is corrupt
Can you let me know when it will be fine to download.

There could have been a problem during download, try again. This is a
lot of data, maybe just download the bootonly iso and install using ftp.
