A NOTE has been added to this issue. ====================================================================== http://www.dbmail.org/mantis/view.php?id=1043 ====================================================================== Reported By: jamesgreig Assigned To: ====================================================================== Project: DBMail Issue ID: 1043 Category: POP3 daemon Reproducibility: random Severity: crash Priority: normal Status: acknowledged target: ====================================================================== Date Submitted: 11-Feb-14 11:23 CET Last Modified: 12-Feb-14 14:12 CET ====================================================================== Summary: exited on signal 11 Description: Since rebuilding a number of dbmail machines onto FreeBSD 9.1 and 9.2 with dbmail 3.1.10 we are seeing random crashes of the pop3d daemon as below:-
Feb 11 09:09:11 redacted-db-4a kernel: pid 1577 (dbmail-pop3d), uid 65534: exited on signal 11 Each time it fails on signal 11. ====================================================================== ---------------------------------------------------------------------- (0003637) jamesgreig (reporter) - 11-Feb-14 12:51 http://www.dbmail.org/mantis/view.php?id=1043#c3637 ---------------------------------------------------------------------- Currently using libzdb from ports in freebsd version:- libzdb-2.11.3 and libevent2 from ports - libevent-2.0.21-stable ---------------------------------------------------------------------- (0003638) jamesgreig (reporter) - 11-Feb-14 17:00 http://www.dbmail.org/mantis/view.php?id=1043#c3638 ---------------------------------------------------------------------- this should actually be a crash but I failed to mark as a crash when I submitted it. ---------------------------------------------------------------------- (0003639) alan (reporter) - 12-Feb-14 13:23 http://www.dbmail.org/mantis/view.php?id=1043#c3639 ---------------------------------------------------------------------- Alas with my limited testing I'm unable to reproduce this bug. Would it be feasible to get a backtrace after building a debug version? (adding WITH_DEBUG_PORTS=mail/dbmail to /etc/make.conf) ---------------------------------------------------------------------- (0003640) jamesgreig (reporter) - 12-Feb-14 13:50 http://www.dbmail.org/mantis/view.php?id=1043#c3640 ---------------------------------------------------------------------- Hi Alan, Getting it on 2 machines. Unfortunately they're live so it's a bit tricky but will see what I can get. I've enabled debugging in dbmail itself to see what I can get. If it fails again i'll rebuild one of them as above. ---------------------------------------------------------------------- (0003641) jamesgreig (reporter) - 12-Feb-14 13:54 http://www.dbmail.org/mantis/view.php?id=1043#c3641 ---------------------------------------------------------------------- Presume this isn't relevant:- http://www.gossamer-threads.com/lists/dbmail/users/34008 though admittedly libzdb in this instance is version 2.11.3 ---------------------------------------------------------------------- (0003642) paul (administrator) - 12-Feb-14 13:55 http://www.dbmail.org/mantis/view.php?id=1043#c3642 ---------------------------------------------------------------------- James, the thread you mention only affects imapd. Getting a debug trace on the crash would help. ---------------------------------------------------------------------- (0003643) jamesgreig (reporter) - 12-Feb-14 14:12 http://www.dbmail.org/mantis/view.php?id=1043#c3643 ---------------------------------------------------------------------- Oddly the last 2 deaths on one machine were the following (different signals):- Feb 11 22:13:45 mail4-db-3a kernel: pid 78837 (dbmail-imapd), uid 65534: exited on signal 6 Feb 12 11:54:32 mail4-db-3a kernel: pid 2346 (dbmail-pop3d), uid 65534: exited on signal 10 This particular machine was running fine with with 3.0.2 Issue History Date Modified Username Field Change ====================================================================== 11-Feb-14 11:23 jamesgreig New Issue 11-Feb-14 12:51 jamesgreig Note Added: 0003637 11-Feb-14 17:00 jamesgreig Note Added: 0003638 12-Feb-14 13:23 alan Note Added: 0003639 12-Feb-14 13:50 jamesgreig Note Added: 0003640 12-Feb-14 13:54 jamesgreig Note Added: 0003641 12-Feb-14 13:55 paul Note Added: 0003642 12-Feb-14 13:56 paul Severity minor => crash 12-Feb-14 13:56 paul Status new => acknowledged 12-Feb-14 14:12 jamesgreig Note Added: 0003643 ====================================================================== _______________________________________________ Dbmail-dev mailing list Dbmail-dev@dbmail.org http://mailman.fastxs.nl/cgi-bin/mailman/listinfo/dbmail-dev
