I did and the following lines appear each time I'm starting dovecot:

May 25 17:58:37 vm3 dovecot: Dovecot starting up
May 25 17:58:38 vm3 dovecot: Auth process died too early - shutting down
May 25 17:58:38 vm3 dovecot: child 2316 (auth) killed with signal 11
May 25 17:58:38 vm3 dovecot: child 2317 (login) killed with signal 11

I tried different things like replacing pgsql by plain passwd, with no
success.
