Hi Timo,

I'm unable to get core dump from doveadm, I start dovecot after run 
"ulimit -c unlimited" and set echo "/tmp/%p" > 
/proc/sys/kernel/core_pattern, so core dumps is enable:

Oct 13 12:38:02 master: Info: Dovecot v2.1.10 starting up
Oct 13 12:38:18 auth-worker(5000): Info: mysql(localhost): Connected to 
database vpopmail
Oct 13 12:38:18 dict: Info: mysql(109.168.113.139): Connected to

Oct 13 12:38:26 dict: Info: mysql(109.168.113.139): Connected to

database dovecot
Oct 13 12:39:51 dict: Info: mysql(109.168.113.139): Connected to 
database dovecot

but when doveadm stops with "Segmentation fault" I'm unable to find any 
dump file and no information in dovecot.log.

Can you help me?
Thanks
