Hi,
We have ASA 9.8 with active and standby , recently it is observed that fail over happened automatically with failure reason as MIO Heartbeat Failure for both devices (FPR2100) , when searched found that there is remedy as add command app-agent heartbeat interval 3000 retry-count 5 for Bug CSCvh26447 or to upgrade the version. Note this is not a frequent but the occasional incident. So what should be opted as solution.
current config and state
service-policy global_policy global
app-agent heartbeat interval 1000 retry-count 3
# sh failover state
