beware, if you have abrt enabled, it can steal/delete "wrong" core file (/var/log/messages): ... abrtd: Package 'dovecot' isn't signed with proper key ... abrtd: Corrupted or bad crash /var/cache/abrt/ccpp-1278658383-11426 (res:5), deleting We do not ship dovecot 2.0 in Fedora 12, so you have probably your own dovecot installed from source or3rd party rpm, in that case (if abrt steals/delete core file) check you have OpenGPGCheck = no ProcessUnpackaged = yes in your /etc/abrt/abrt.conf if not, change these values and restart abrtd daemon. You will find core file in /var/chache/abrt/ccpp-*/coredump second option is MakeCompatCore = yes in /etc/abrt/plugin/CCpp.conf which will keep core file in place - and add following line in the log/messages: abrt[11432]: saved core dump of pid 11426 to /var/run/dovecot/core.11426 (466944 bytes) NOTE:for official fedora packages, core dumps are always collected by abrt and accessible in /var/cache/abrt/ directory by default, so no need to change anything Michal
