So it's gone to some loop where it keeps calling io_add() and io_remove(). I'm guessing it's because of doveadm command handling issues, since there's some weirdness in the code. Although I couldn't figure out exactly why it would go to infinite loop there. But attached a patch that may fix it, if you're able to test. We haven't noticed such...

I'm using dovecot 1.0.alpha4 on a freebsd 5.3 i386 system. Dovecot is configured to use mysql authentication and I'm running mysql 5.0.15 . Everything works fine, but after a period of inactivity (20-30 minutes ) when I connect and try to authenticate it just hangs. I noticed that the dovecot-auth worker process is not running anymore... from looking at the source code I understand that
