High latencies after HA failover

L0 Member
Goodmorning, i have a cluster with two PA3060 running panos 9.1.16.
We are about to upgrade to 9.1.16.H3 due to certificate expiration.
I had already updated the Secondary (passive) node to 9.1.16.H3 without issues 1 days before .
 
The second step was to upgrade the Primary node. 
Before to upgrade the active node i requested the failover, the secondary node became active and all the network started to slow down.
I had many costant pings windows on different zones of the networks and i've observerd a strong increase of latencies (1000-3000). Most part of network services became unreachable due to high latencies but Firewalls management port were still fast and reachable.
In the secondary (active) node i noticed Management plane with low percents but traffic plane at 100%
 
When i resumed the primary node state to active the issue disappeared.

did you collect information like `show session info` and `show running resource-monitor` or `debug dataplane pool statistics`? 

 

you're not giving us much to work with here 🙂
