9.1(4.5)

Description (partial)

Symptom:
An ASA taking over the Active role due to an interface failure of any port in Module 1 may get stuck in a failover synchronization loop. This will cause a traffic outage as the unit that should be Active will get stuck in a failover loop, and the other unit will be in the Standby state.

Conditions:
This only occurs if interface monitoring if the onboard ports are used on the device in module 1. It is primarily observed  if the card in module 1 is only used for ports but not for services (ie. CX, IPS, etc)
