Bug Description
SRU information:
See below for detailed description. tl;dr: Dovecot continuously panics, preventing local delivery. Mail clients cannot connect or read their mail. This is a critical crash which is not fixed by restarting dovecot, rebooting, or anything else.
[Test Case]
I don't have a way to reproduce it or trigger the problem. The start of the relevant thread in upstream's mailing list is here: http://
[Regression Potential]
Seems low. After having applied a local build of the 12.04 dovecot package with this patch applied (see merge proposal), the bug appears fixed, with no regressions observed so far.
I'm seeing this now in my 12.04 /var/log/mail.log:
Jun 27 16:25:19 wreckers dovecot: imap(barry): Error: Raw backtrace: /usr/lib/
Jun 27 16:25:19 wreckers dovecot: master: Error: service(imap): child 1993 killed with signal 6 (core dumped)
This mailing list message

which I am now testing.
This only affects 12.04's version of dovecot 2.0.19. I believe this patch has already been applied to the dovecot 2.1.7 version which is in Quantal.

So far, that patch does seem to fix the crashes, and dovecot appears to be working again on my production 12.04 system. I'll now submit a merge proposal and SRU request.
