Hello,

dovecot-1.0.3 on Fedora 6 works perfect in general but sometimes the system
becomes unresponsive and the log file shows tons of messages like this:


  ...   imap-login: Disconnected: Shutting down: 127.0.0.1, secured
  ...   pop3-login: Disconnected: Shutting down: aa.bb.cc.dd


Restarting dovecot helps, but what's behind?
What can I do to prevent this?
