WM6 ActiveSync issues?

[bennytheshap]

Greetings!

My place of work has a Zimbra server (currently running 4.5.5, scheduled for 4.5.6 upgrade shortly). I have a HTC Mogul/6800 on Sprint (EVDO). It doesn't seem to be able to maintain a DirectPush connection to the server. That is, it makes one, stays up for a few minutes, then the ActiveSync screen says when it was last connected. If I manually sync it'll stay up again for a few minutes.

Is this a known issue? Is it something that will be fixed when we upgrade to 4.5.6?

Here's the ActiveSync log from my device. Thanks!:

Anything in the sync.log in /opt/zimbra/log ? We've seen some networks like Cingular/ATT drop the connection as frequently as once a minute. Sometimes it will depend on your plan. I would start with looking at the Zimbra log and try to see when/if the phone is sending a ping request and how often.
