Hi!
Can you try follow this guide to get a core dump
https://www.dovecot.org/bugreport-mail
then provide
gdb /usr/lib/dovecot/auth /path/to/core
bt full
on it. Would help narrowing down that bug.
Also doveconf -n could be useful.

I narrowed the probelem down to the warnings
Warning: service auth { client_limit=128 } is lower than required under max. load (768) Warning: service anvil { client_limit=256 } is lower than required under max. load (643) These messages disappear after changes in the auth and anvil config but I ran into the following problem:
dovecot[355234]: master: Dovecot v2.2.36.4 (baf9232c1) starting up for imap dovecot[355234]: master: Error: service(auth): command startup failed, throttling for 2 secs dovecot[355237]: auth: Fatal: master: service(auth): child 355242 killed with signal 11 (core dumped) dovecot[355234]: master: Error: service(auth): command startup failed, throttling for 4 secs dovecot[355237]: auth: Fatal: master: service(auth): child 355256 killed with signal 11 (core dumped) dovecot[355234]: master: Error: service(auth): command startup failed, throttling for 8 secs dovecot[355237]: auth: Fatal: master: service(auth): child 355271 killed with signal 11 (core dumped) dovecot[355234]: master: Error: service(auth): command startup failed, throttling for 16 secs dovecot[355237]: auth: Fatal: master: service(auth): child 355285 killed with signal 11 (core dumped) dovecot[355234]: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot[355237]: imap-login: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot[355237]: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot[355237]: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) dovecot[355237]: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill)
I guess the solution is simple but I can't find it :-(
