Running multiple GW8 SP2 PostOffices on OES2 SP2, using LDAP authentication.
LDAP pool set with two LDAP servers.

Randomly some POA starts giving login errors, LDAP Error: 80 on the logfile.
Both LDAP servers are fine and others POAs continue to work.
Restarting the problem POA fixes the problem - until it comes back someday.
