Problem: The BlackBerry device client shows a Server Response Timeout error in the event status log ().
Explanation: In general, a "Server Response Timeout" error means that the server did not respond to an HTTP request in a timely manner. This typically indicates that the request was too large or the network too slow to complete a request before either the BES or the network layer on the client timed it out. This could be caused by the BES/MDS configuration being set to a timeout that is too short for the kind of requests being sent (for example, very large uploads or downloads). Additionally, a slowly responding Unwired Server (perhaps because it is overloaded) could cause the same error.
Solution: Check Unwired Server, the network, and BES/MDS configuration settings, and tune for better performance. See System Administration, the Performance Tuning and Testing section.
