Upgrading Dovecot server above 1.1.16 version leads to many zombie processes that could eat resources. After upgrade Dovecot runs dovecot-auth processes which starts zombie: dovecot 10334 0.0 0.0 0 0 ??

The longer Dovecot runs more zombies are created, rate is one per 30 seconds. Additionally, each connection to Dovecot leaves one more zombie process. >How-To-Repeat: Install Dovecot 1.2.x from ports on Alphaserver 1200 and run it with default dovecot.conf (even taken from examples directory). No mather if you use POP3 or IMAP. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
