It's as items arrive for peak as well as off peak as I am a 24/7 guy for work. This is during peak hours as well. Push continues to work for a few minutes after a manual sync, during which time any new email is delivered. After a few minutes the push function ceases to work at all. Again a manual sync will restore functionality for a limited time.
AFAIK ActiveSync uses long polling with the exchange server to keep a TCP connection open for the push. It's as if the tunnel is being killed and not re-instantiated until a manual sync is done. ActiveSync should detect this when it can't reach the server on it's regular polling interval to verify the tunnel is still alive and re-establish the connection. This doesn't appear to be happening though. This has only happened with 2.5 ROMs so far for me - no issues with 2.1 or any other WM 6.1 or 6.5 ROM across 3 devices.
