ff is killing named

[Christopher Barry]

Hi all,

not sure if this is the right list, if not please advise.

I run my own nameserver on my box, and have for many years.
When running firefox (rebranded to iceweasel in Debian) v31.1.0, and
hitting certain websites/pages (most noticeably amazon or ebay, but it
can pretty much randomly be any site), named (BIND 9.9.5-4.1-Debian)
will gag and fall over with the following syslog dump:


Oct 11 16:45:19 monolith named[26038]: mem.c:1321: REQUIRE(ptr !=
((void *)0)) failed, back trace
Oct 11 16:45:19 monolith named[26038]: #0 0x7f3f05e5322d in ??

Oct 11 16:45:19 monolith named[26038]: exiting (due to assertion
failure)

exited, code=exited status=1

I spent a good deal of time researching this issue, thinking it was a
named bug, and could not find anything about it. I'm running Debian
Jessie, which recently changed to use systemd (and I'm not sure it's
not related somehow).

Recently, I was trying to get to a page on ebay, and every time I
clicked this link:
http://contact.ebay.com/ws/eBayISAPI.dll?ShowCoreAskSellerQuestion&redirect=0&requested=22newcentury&iid=321536360296
named would crash hard and FF would fail to find the site.
It's 100% repeatable.

I decided to try chromium, to see if the error could possibly be related
to FF somehow, and sure enough chromium never crashes named and goes to
the link. I cannot get chromium to crash named.

I have never had this kind of issue before with Iceweasel/Firefox, and
it's very confusing what is causing it. I *really* do not want to use
chromium, so please let me know how we can proceed to isolate and
remedy this issue. I'm up for any testing you can think of.

Thanks!

Hi Christopher - I think you need to start with the bind devs for this one,
given that it is bind that is crashing. Maybe it has a no daemon mode (-D?)
and you can start it under gdb and get a stack trace - that would probably
help them. If they indicate that there is something we should be aware of
on the firefox side, please circle back.

Thanks!

Hi Patrick,

Thanks for replying.

I had just updated my box the other day, thinking there may be an
update to bind, but bind was not in the package list. Then today I sent
the message below to the list after noticing chromium had no problems.

After sending the email, I though I'd try to update again, just to see.
Sure enough, bind was an update. I updated it, and so far no crashing
going to the site that was crashing 100% of the time.

Sorry for the noise, weird issue, but it appears to be resolved now.
lesson: update and test *immediately* before sending to a list :)
