Hi Guys,

today our Zimbra install is doing strange things.

It is suddenly running slowly for a start and is throwing up errors and timeouts.
I checked the status of the Services and was told that the mailbox was stopped and that Tomcat was not running.
I stopped and started the Services and they all started up again correctly.
I hoped that was the end of it but as User told me shortly after that it was still acting strangely. Checked the Services again and they are all on.

Have now had an error myself again, sometimes when I try to open a new compose window I just get an HTTP timeout error and other times I get the message below;

method - AjxRpc.prototype._invoke
detail - [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.send]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://192.168.x.x/zimbra/js/Ajax_al...v=071016181552 :: anonymous :: line 1439" data: no]
code - AjxException.UNKNOWN_ERROR
msg - Unknown Error

At other times it works fine!
Any clues please Guys, do you think it could be the physical server itself or Network connection? (no other signs of this on the Network though)
Or does the error message indicate something about Zimbra itself.
