working install found shut down and won't restart!

[jptech]

I installed it and configured it.
it ran just fine for two days.
I left for a week and came back.
I found zimbra shut down and wouldn't restart.
the restart is failing on ldap.

where do I start to troubleshoot?
what log files should I check?

Well, let's start by seeing your errors. Does it give you a specific error while starting ldap?

What's in mailbox.log and zimbra.log located in /opt/zimbra/log and /var/log respectively.
