HA FTD fails over when deploying VDB updates

mickyq · ‎09-21-2023

A pair of Firepower 2140s in HA configuration failover when deploying the VDB updates. Failover history shows:

Inspection engine in other unit has failed due to snort failure

my understanding is the deployment will cause inspection interruption but why does it cause the failover.
