Hello everyone,
I have exactly the same problem.
Update from 11.1.4-h1 to the preferred release 11.1.4-h7 with a PA440 firewall cluster (active/passive).
Immediately after the update I had almost 100% CPU on the management plane on both firewalls.
At first I thought that it might be related to some background tasks after the update and left it like that for 24 hours and observed it. To no avail, the CPU load remained very high.
I then downgraded both firewalls to version 11.1.4-h1 and immediately afterwards everything was fine again. The CPU load is now back to its usual low level.
I'm surprised that no one else has reported this error...
Best regards,
naardes
