You LDAP service is broken. Until that is fixed, I would recommend a nanny script to restart postfix until that happens. Otherwise you will need to front the broken server with another service that will clean-up for you on the LDAP side. Good luck. It is much easier to fix the broken directory service than re-start properly functioning software. Regards, Ken
