Hi,
I get these errors with dovecot 1.1.13 in my logs:
dovecot: Mar 27 12:00:34 Error: auth-worker(default): *** glibc detected *** dovecot-auth: double free or corruption (!prev): 0x00002b30d5a7dd90 *** dovecot: Mar 27 12:00:34 Error: auth(default): worker-server(jan,147.251.48.141): Aborted: Worker process died unexpectedly dovecot: Mar 27 12:00:34 Error: child 21838 (auth-worker) killed with signal 6 (core not dumped) dovecot: Mar 27 12:10:23 Error: child 22711 (auth-worker) killed with signal 11 (core not dumped) dovecot: Mar 27 12:10:23 Error: auth(default): worker-server(thomas,209.85.146.140): Aborted: Worker process died unexpectedly
Haven't seen this with previous versions.
But somehow I fail to get the core dump. I do 'ulimit -c unlimited' before starting dovecot, I set
soft core 8192
in limits.conf, /proc/sys/kernel/core_pattern is set to /tmp/core.hard core 8192
