Hi mates
Does someone meet performance issue after upgrade to R80.40?
At my 2 customers I faced out the same performance issue when I upgraded the cluster from R80.xx to R80.40 last take.
For both I had to downgrade to the previous version because critical environments where I cannot wait for TAC investigation.
this is the reason why I'm sharing my findings
In both cases I see the active cluster member suddenly has more CPUs 100% usage.
When it happens the gateway is unresponsive and the TOP output shows high usage for "watchdog" daemons.
Reverting to previous version, the performance on the gateway is as expected.
