Re: Core dump during UID Search

22 Nov 2018


      Some extra information I was able to gather:
dovecot: imap(xistence@0x58.com)<5991><4umat4J6acYmAQKCQwG+/BBkGhFix4Sh>: Panic: file mail-storage.c: line 1951 (mailbox_get_open_status): assertion failed: (box->opened)
This is apparently dumped to dmesg right before the core dump happens.

I’m using the package available from the quarterly repository.
I will build from ports and report back.

I'm the dovecot maintainer for FreeBSD.  To get DEBUG symbols, if you are building your own package, add:
WITH_DEBUG_PORTS=mail/dovecot
To your /etc/make.conf, and the symbols should then be available.

I really wish I could get some better backtrace information, but unfortunately this is it :-(
Did you install the debug symbols for Dovecot? On Debian, those are
available as a separate dovecot-dbg package. I'm not sure how FreeBSD
provides this.

Stephan.

Hey all,
I keep finding core dumps of the IMAP process on my FreeBSD 11.2, however the backtrace is not very useful:
Core was generated by `imap: [xistence@0x58.com 2601:282:4301:befc:1cfb:807f:e527:5a3b UID SEARCH]'.
Program terminated with signal 6, Aborted.
