Can you somehow get a core file and get backtrace from it?
Aki
The bug happens not very often, it might need a week to get a core file.

I got a core file this morning.
opening it with gdb I get this:
(gdb) core imap.core Core was generated by `dovecot/imap'. Program terminated with signal 6, Aborted. #0 0x0000000011c1347a in ?? () (gdb) bt #0 0x0000000011c1347a in ??

Doesn't look clean at all.
let me know if I should upload the file somewhere.

That is not that helpful. Did you install debug symbols for Dovecot? This is usually a separate package. It all depends on your OS. I am not familiar with FreeBSD.

for FreeBSD you can add to /etc/make.conf: WITH_DEBUG_PORTS=mail/dovecot mail/dovecot-pigeonhole
and rebuild the packages. (from the FreeBSD port maintainer, me).
