My Exchange getting the below error
=========================================================================
The average of the most recent heartbeat intervals [494] for request [Sync] used by clients is less than or equal to [540].
Make sure that your firewall configuration is set to work correctly with Exchange ActiveSync and direct push technology. Specifically, make sure that your firewall is configured so that requests to Exchange ActiveSync do not expire before they have the opportunity to be processed.

For more information about how to configure firewall settings when using Exchange ActiveSync, see Microsoft Knowledge Base article 905013, "Enterprise Firewall Configuration for Exchange ActiveSync Direct Push Technology" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=905013).

It's no problem as long as no one is complaining.  You can up the time out of port 80 and 443 to 20 minutes in your firewall.  Also try changing the connection timeout in IIS to 20 mins for the default website
