We're running Dovecot 2.0.2 and sometimes a user creates several imap- prozesses, all of them hanging with the UID-command, using 100% of the CPU resources:
root@mail:~# ps ax | grep UID 8005 ? R 266:52 dovecot/imap [user@example.com 192.168.5.5 UID] 10342 ? R 250:33 dovecot/imap [user@example.com 192.168.5.5 UID] 10539 ? R 248:28 dovecot/imap [user@example.com 192.168.5.5 UID] 11150 ? R 245:03 dovecot/imap [user@example.com 192.168.5.5 UID] 11525 ? R 243:55 dovecot/imap [user@example.com 192.168.5.5 UID]
This situation is triggered by two users only. Looks like their mailclient is sending a special command, that triggers the crash.
Is it a bug or another problem?
Is this a bug already fixed in Dovecot 2.0.3?
- Fixed an infinite loop introduced by v2.0.2's message parser changes.Unfortunetaly I can't try an update at the moment. :-(
