dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11
Still Trying to track down a dovecot issue ....
The error message is:
dovecot: auth-worker: Fatal: master: service(auth-worker): child XXXXX killed with signal 11 (core not dumped - set service auth-worker { drop_priv_before_exec=yes })
The setup is dovecot 2.2.29.1 with passwd and mysql auth db's and a very basic config.
both authentications work ... the symptom is that after a connection is made the auth worker loads and emails are downloaded and everything "is fine". However, about 30 second to a minute after the connection is done the process dies with the error message. Then the process starts all over with on the next checking of email ,but again everything "works" just seeing this error and the process dieing each time?
enabled all extra verbose logging ,but nothing gives any clues....
Tried to enable core dumps ,but couldnt get core dumps to work ?
The only thing is that a recently pkgsrc (netbsd) update create 2 packages, one for dovecot and one for mysql plugin , sense then now this error appears.
,but it appears the .so lib files are installed and linked correctly.
Double checked all file permissions and user permissions as well as chroot , etc, etc, ,etc....
cant seem to narrow this one down ....
any ideas on trouble shooting would be great ....
even tried running a trace with gdb -p on the process ,but it just dies with a signal 11 ....
anybody have any ideas how to trouble shoot this or is this a bug in the software ....
help !!

Hi!
As mentioned before, your issue unfortunately cannot be solved without core dump. Please try https://www.dovecot.org/bugreport.html if doing all this allows you to get a core dump. Unfortunately there is no other solution at the moment, or some other way to debug this further.
