Hello list,
I'm using dovecot 1.0.2 on OpenBSD 4.1. About every month, dovecot will just stall, without any error messages. The processes
are still running, the network ports are open, but the login just hangs.
The following error message does occur on a very regular basis:
Aug 15 00:52:37 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
Aug 15 01:08:08 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server

Aug 15 01:54:09 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
Aug 15 02:09:10 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
Aug 15 02:24:40 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
Aug 15 02:39:41 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
Aug 15 02:55:12 mail dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
(stalling from here)
The LDAP directory is Active Directory and is not used as userdb, only as passdb.
Thanks,
Bert
