Event Policy expiry delay during outage

In the described scenario the active event will expire.

Active events are stored in the primary DB; if an active event does not get an occurrence count increase from another trigger of the alert matching that entity (ex. device) and that event policy, which cannot occur if the device that would trigger that alert resides on a Collector to which the DB cannot communicate and that event policy has an expiration, then expiration will occur as the timer is based on the last occurrence of that event.
