Hajo,
From the looks and sounds of things your Dovecot installation and configuration is crashing without creating a dump. What happens prior to the aforementioned log entries?
Thanks, Dan

Hello,
we have some problems with users who report connectionproblems to dovecot sometimes. According to the logs there are dovecot reloads at this times. Seems that a reload also causes dovecot to shut all imapconnections down:
Jul 16 13:31:40 myhostname dovecot: master: Warning: SIGHUP received - reloading configuration Jul 16 13:31:40 myhostname dovecot: imap: Server shutting down. bytes=251/675
I tried to reload by initscript or sending -HUP manually to pid, dovecot is shutting down imapconnections and i think this is the reason for users to report this problems with some clients. This seems to be new with versions 2.x, i have some old 1.2.x dovecots running and cant find "Server shutting down" in their logs after reload.
I have still potential to reduce reloads, but cant avoid them completely. Is there a workaround?
Thanks, Hajo
