| Event Information | According to Microsoft: EXPLANATION: This problem may occur when there is insufficient bandwidth or many network errors.It may be due to heap corruption when two or more threads in the message transfer agent (MTA) try to access the same data structures without proper synchronization. This problem has been particularly noted in networks in which many associations are being opened and closed between MTAs. Frequently, these MTA failures are associated with slow and unreliable connections. USER ACTION: Use Network Monitor to capture Network Traces, then view these traces from Network Monitor for any network issue. Contact Microsoft Product Support Services for assistance.
