Since upgrading to 6.0.x, there is nothing in /opt/zimbra/log/mailbox.log or /opt/zimbra/log/audit.log. This is very troubling since it makes it impossible to diagnose some of the "a network service error" messages we seem to get quite frequently. I have tried stopping Zimbra and running (as root) the zmfixperms script which has not solved the problem. I have no idea how to diagnose this since usually those two log files help diagnose most issues with Zimbra
Any help would be greatly appreciated.
