Description (partial)

Under heavy load, the data-plane connection between the ASA And the SourceFire module may be marked as failed in rare situations. This may cause a failover event since the module will be marked as un-healthy.

This is seen in deployments where a SourceFire FirePower module (physical or virtual) is installed within an ASA and there is a high rate of traffic being exchanged between the ASA and the module.

Does anyone know if 9.2.3 for the ASA fixes this issue?
