Hii

I have zimbra ldap server which has been run for 2 month. Today, I found that my zimbra ldap suddenly stopped..

file: /var/log/messages
Jul 30 08:21:53 xxx01 zimbramon[28791]: 28791:info: zmmtaconfig: gacf ERROR: service.FAILURE (system failure: ZimbraLdapContext) (cause: javax.naming.CommunicationException svr01.forestindo.local:389)

Notes: the other zimbra service work properly, just zimbra ldap stopped.
It's happened twice..
Do you have any idea about the problem and solution about this?

Thanks before and I appreciate your help..
