Cannot connect to server

[ezu]

From past few days, I get this error very often.

Cannot connect to server.

msg: Cannot connect to server.
code: EMPTY_RESPONSE
method: SearchRequest
detail:

This usually comes when I click on a different folder from the one I am viewing. It will usually disappear if I shutdown Zimbra and start it again. What could be causing it and what do I do to resolve it ?

Did you figure anything out on this? We're seeing a user with this error on occasion and having problems finding anything in the logs.

I had the same problem. I turned off the firewall and checked my router. Nothing. Then I unloaded trend antivirus. Now it works.
