Re: dovecot auth-worker error happens when I enabled the dovecot to consider both the system account and the MySQL virtual mailbox databases.

I've found this for a long time. But I didn't examined "sudo apt-get libpam-smbpass" till now... Doing that, my problem is "solved"... http://ubuntuforums.org/showthread.php?t=2246951&highlight=dovecot+auth+worker libpam-smbpass has a bug of memory leak. I cannot tell surely....But it returns the error... So the auth-worker would get down by that. Dovecot uses both my system accounts and MySQL virtual mailboxes now...
