many thanks, this is very helpful
I don't seem to have this lockup anymore.
Don't know what was happening. I've run
it now several times on 3 different ia64
current (different revisions) boxes, with
disks of different speed, and can't reproduce.
My script was very crude, of course.
I'll try sysutils/libchk
thanks again

This will probably do closer to what you actually would want to look for.
Writing to /dev/zero ... I don't know never tried it since /dev/null is
usually the standard place to throw trash.
#!/bin/sh
for file in `find /*bin /usr/*bin /usr/lib* /usr/local/*bin -type f` do
echo $file
ldd $file >>/root/ldd_results 2>/dev/null
done
The problem with your script is that it finds most files that it can not
or is not useful to run ldd on and leaves you junk in return.
It might be more useful if you searched for dynamically linked ELF
binaries to run ldd against like the following.
=== Script starts here ===
#!/bin/sh
SEARCHPATH="/*bin /usr/*bin /usr/lib* /usr/local/*bin"
trap 'exit 1' 2
check_libs() {
for spath in $SEARCHPATH; do
for ifelf in `find $spath -type f`; do
ldd `file $ifelf | grep dynamically | cut -f1 -d:`
done
done
}
check_libs 2>/dev/null
=== Script ends here ===
The above will find all type ELF * that are dynamically linked within the
SEARCHPATH variable and run ldd on them and print the results to stdout.
Obviously since you are going to have thousands of files being questioned,
stdout is not going to be useful.
So with the about stated:
save the script to: checklibs.sh
run with: "sh checklibs.sh >/root/checklibs_output"
or: "script /root/checklibs_output checklibs.sh"
> After the upgrade to r205248, the script

Of course... to many open files or processes in wait. SSH already has the
information it needs loaded into memory, that's why you can get sort-of-in
ZFS file-system perhaps ?

The above edited script should help to limit disk usage and too many open
processes that causes your machine to bog down like that. This script does
have its limitations and there is one bug in it... Ill let you figure out
how to get rid of that bug but it really does not effect the intended
output so I left it alone and sent error output to fd/2.
The limitations you'll find is how many files that ldd(1) or file(1) can
handle at one time. But if you specify specific paths like already in
SEARCHPATH then you will most likely never see this unless the files in
/*bin grow to be over max number of files that file(1) or ldd(1) can
handle at one time. Shortly said... use direct paths or short globs like
above.

Standard Disclaimer: NONE OF THIS CONTAINED HEREIN "THIS MESSAGE" EXCUSES
ANY OF THE UNEXPLAINED DISK LOCKING THAT IS GOING ON AND THE INFORMATION

FWIW I've been seeing some performance issues with iir(4) and mfi(4)
backed UFS2 with softupdate filesystems on my new machine with some
other drivers loaded on my system [a PCI based em(4) card and
nvidia-driver enabled card -- which uses GIANT locking still].
Machine is Core i7 on an ASUS W6T Professional MB, 12GB RAM, with
debug symbols, ddb, kgdb, anti-reslock contention manager, (no
witness) etc.
I don't have much other than that to provide at this time, but it
might help to see if and when there's an overlap in the drivers noted
here.
Thanks,
