KCNS Failed to Perform a Routine Synchronization

Issue

Remote sites receive the following error message:

2/4/2011 12:55:05 PM, (2500) ACISV: [4136] KdoLib: The running module failed to
perform a routine synchronization and has been terminated. You can recover the batch
in progress by starting the Batch Manager. Please contact the central site
administrator for assistance., Station ID: 113m01 (D-MXL90609YM).

Additionally, the Kofax Capture Network Services (KCNS) Remote Synchronization does occasionally complete successfully and transfer batch-level data between Remote and Central sites.  

Cause

It was observed in one situation that there were two KCN services. One of them worked and one didn't. The working service was continually overloaded by 300 Remote Sites. The occasional syncs that were serviced by the working KCN service were successful.
