dovecot - Mar 2009 - 1.11 bug?: file client-common.c: line 25 (client_unlink): assertion failed: (clients_count > 0)

Hi,

I got below log in last 2 days, I have to restart dovecot as pop3-login failed
and service cannot respond.

Mar 26 14:19:31 Info: pop3-login: Disconnected: Shutting down (auth failed, 1
attempts): method=PLAIN, rip=x.x.x.x
Mar 26 14:19:31 Info: pop3-login: Disconnected: Shutting down (tried to use
disabled plaintext auth): method=??<B7>
Mar 26 14:19:31 Panic: pop3-login: file client-common.c: line 25
(client_unlink): assertion failed: (clients_count > 0)
Mar 26 14:19:31 Error: child 31902 (login) killed with signal 6 (ip=x.x.x.x)

My system info:
dovecot -n

  userdb:

  userdb:

We're using Maildir format, no NFS. Any help/clue is appreciated.

Thanks,

Any help on this? It happens more frequently :(. Is this related to LDAP
authen?

Thanks,
