FMC Update increased Snort memory to FDT; Deployment failed

Hello everyone,
We have updated our FMC from v7.3.1.1 (build 19) to v7.3.1.1 (build 83), after the first deployment to our FDT-HA (both Firepower 2120) is on Active FDT double as much memory allocated to Inspection Engine (snort3), on the Passive this is not the case.
Since then the failover breaks down during Config Deployment and the Deployment failed.

I know SNORT3 required some additional memory and eventually that should come to normal.

if it only effecting when the policy published and not effecting any traffic - then i will give some time and see if that come to normal condition.

if that is effecting - then i will raise an TAC case for investigation.
