I had been running zimbra 5.0.8 on an ubuntu 6.06 box for quite some time and everything was working. One of my coworkers changed something in the admin web panel and since then zimbra stopped working. He doesn't have any idea what he changed. Now, I can not connect via imap/pop/webmail nor to the web admin panel.

zmcontrol status shows

Code:
zimbra@mail:~/bin$ zmcontrol status
