I have been using Zimbra for 2 works and worked flawlessly until I could not login for some reason.
After I su to zimbra on the console I get the following:
[zimbra@mail user]$ zmcontrol status
Calling GetServiceInfoRequest (mail.mydomain.net)

Soap call failed: 500 Can't connect to localhost:7777 (connect: Connection refused) at /opt/zimbra/zimbramon/zmcontrol line 230
[zimbra@mail user]$ zmcontrol start 
Calling start (mail.mydomain.net)

getservbyname failed for tcp at /opt/zimbra/zimbramon/lib/Zimbra/Mon/Logger.pm line 50

[zimbra@mail user]$ vi /opt/zimbra/zimbramon/lib/Zimbra/Mon/Logger.pm
I am not sure how to solve the problem. I have all my personal mails in Zimbra
now and I do not want to lose them.
