Description of problem: cupsd is randomly segfaulting on a number of machines Version-Release number of selected component (if applicable): cups-1.2.1-1.7 How reproducible: Random Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Here is whats in dmesg from three machines all FC5/x86-64: cupsd[1429] general protection rip:2ad4ce361600 rsp:7fffdd3b29d8 error:0 cupsd[14780]: segfault at 0000000000000021 rip 00002ae20f80b6ac rsp 00007fff9bb26350 error 6 cupsd[27384]: segfault at 0000000000000001 rip 00002b0c31d27040 rsp 00007fff799e4108 error 4 cupsd[22506]: segfault at 0000000000000001 rip 00002ada30b7d5e0 rsp 00007fff7ab931b8 error 4
Please try this test update: https://www.redhat.com/archives/fedora-test-list/2006-July/msg00555.html Does that fix the problem? How frequently does this happen?
Any news on whether the test update fixes the problem?
I'd tentatively say yes. It's been a few weeks and no problems. Cheers.
Just had cups die on another machine around here. The machine printed someting then wouldn't print no more... FC5, cups-1.2.2-1.1, which seems to be the same version as the update I'm running.
Any clues about what happened? Any dmesg messages look relevant? Please attach the /var/log/cups/error_log from that machine (or at least the last few lines of it..).
From dmesg cupsd[1660]: segfault at 0000000000000000 rip 00002afffff9b040 rsp 00007fffab8ed1c8 error 4 I've attached all the entries for today from the cups error_log (I'm seeing a lot of references to a printer which is long gone. Possibly some other machine is trying to print to that. But I don't think thats causing cups to die) This looks like the few line before and after death.

Created attachment 134399 [details] Snippet of cups error_log
Please change /etc/cups/cupsd.conf so that the 'LogLevel' line reads: LogLevel debug2 That way when it happens again we'll have lots more information about what went wrong. Thanks.
OK. Done. Cheers,
Oh, I forgot to mention -- if this is on an always-on server you'll need to restart cups as well (/sbin/service cups restart). Thanks. Let me know if/when it happens again.. (I'll leave this in NEEDINFO until then)
Closing. Please re-open if this happens again.
