Symptom:
After integrating PC4HCS with NOC, customer started seeing the following issues:

1.       Duplicate events being received. It was observed that some events were being resent 1 minute after the initial was being received causing a double event.
2.       The volume of NBI events being received by the PC4HCS seems to be a compounding amount of older events lost in a limbo state. In 24 hours we received ~ 6,000 events, of which the majority were old event that seemed to be resent continuously at a 5 minutes interval. These old events either we no longer present or had no reflection in Prime Central's current displayed events.
