When the FactoryTalk Historian ME systems are up and running and connection to
the data source is lost, a message similar to the following will be logged:
0 DataCollection 28-Dec-09 19:00:47 [ERROR] HandleNotification()
detected erroneous return condition from notify_on_event API.
This message is logged once for every 300 errors to keep the log disk space from
being flooded with too many error messages.
