Urgent: Not receiving emails

[rjrinternational]

Hi,
Since last few days, I am unable to receive emails. Though I am able to send the emails, but none of the emails are getting received in ZD. I am getting the following error
-----------------------------------------------------------
Failure communicating with remote server. Please try again later.

Debug message: Java heap space

Exception:

java.lang.OutOfMemoryError: Java heap space

If issue persists please post description and debug information here.
-------------------------------------------------------------

Kindly provide a solution asap.
Regards
RJ

Hi, can you find the zdesktop.log under ~/Library/Zimbra Desktop/log. Do you see any exception stack around OutOfMemoryError ? Thanks.
