Hi,

This could happen in following cases :

1) IF alarm is configured as "Acknowledge not required" then in case of return to normal state it automatcially goes from alarm list.

2) If there is burst of AE events under a specific category then alarms get remove on FIFO basis. By default the value for the category will be 10,000.
