dovecot - Dec 2005 - assertion failed: (conn->refcount > 1)

Hi,

Sometimes (happens maybe twice in a day), I have the following errors:

Dec 15 16:10:17 dovecot: auth(default): file auth-client-connection.c: line 33
(auth_client_send): assertion failed: (conn->refcount > 1)
Dec 15 16:10:17 dovecot: child 17152 (auth) killed with signal 6
Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at
default: Connection refused
Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at
default: Connection refused
Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at
default: Connection refused
Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at
default: Connection refused

Dovecot seems to recover though, because afterwards it still works. I did
however notice that the logging-in seemed to hang for a while (some seconds).

Cheers
David
