Can you still reproduce this crash? It would be nice to get its backtrace to get that bug fixed. The core file should be in Dovecot's base_dir (/var/run/dovecot probably). http://dovecot.org/bugreport.html
I tried the core dump method from the above link, but without luck. Here is what I did:
- vi /etc/dovecot.conf mail_drop_priv_before_exec = yes mail_debug = yes # the rest is untouched
- ulimit -c unlimited
- service dovecot restart
- echo 'core.%p' > /proc/sys/kernel/core_pattern
I noticed this in the maillog this morning: Sep 24 07:34:20 mail dovecot: child 492 (auth) killed with signal 11
But there isn't any core dump found in the whole file system. Then I doubted there's maybe some setting problems and did the following: echo '/tmp/core.%p" > /proc/sys/kernel/core_pattern ulimit -c unlimited /etc/init.d/dovecot restart ps aux | grep dovecot-auth kill -s 11 <pid_of_dovecot_auth_found>
And there still isn't any /tmp/core.* found. Is there any other way I can try?
