Cause

The reason for this is that the Synchronization Cycle running every 2-3 minutes utilizes system resources at the operating system level.  Items such as Network Ports which stay active for 2 minutes.

Resolution

In this case, we moved the Synchronization schedule from every 2 - 3 minutes to a synchronization cycle of 10 minutes or greater.  This will reduce, if not completely resolve the issue.
