Hi everyone!

I’m using dovecot 2.3.5. submission-login is crashing many times in a day:

Here is a sample error message:

dovecot: submission-login: Fatal: master: service(submission-login): child 
34247 killed with signal 11 (core not dumped - 
https://dovecot.org/bugreport.html#coredumps - set service submission-login { 
drop_priv_before_exec=yes })

After I added drop_priv_before_exec, I got these error messages:

submission-login: Error: master-service: cannot get filters: 
net_connect_unix(/var/run/dovecot/config) failed: Permission denied
dovecot: master: Error: service(submission-login): command startup failed, 
throttling for 2 secs

How to get submission core dumps properly?

Thank you.


We got a fix for this bug in off-list discussions.

Tracking as DOP-987.

Regards,

Stephan.

If you're using Linux, you could alternatively: sysctl -w fs.suid_dumpable=2

This could be avoided with adding to dovecot.conf:

service config {
  unix_listener config {
mode = 0666
  }
}
