Standby firewall restarting on 11.0.4-h1

L0 Member

Upgraded my 5250 firewall pair last week to 11.0.4-h1 for CVE-2024-3400.  Since then, have seen my secondary/standby firewall reboot twice over the course of a week after a error of "HA Group 52: Dataplane is down: too many children exited".  This never happened prior to this release.


I am currently working with support, just waiting on a response.  Also noticed today that they released 11.0.4-h2.


(PA-3200 Series, PA-5200 Series, and PA-7000 Series firewalls) Fixed an issue where upgrading the firewall to PAN-OS 11.0.4 or PAN-OS 11.0.4-h1 caused the firewall to go into a non-functional state.


Just curious if anyone else is having these kinds of issues....or did I win the "crash lottery"?   Has anyone upgraded to 11.0.4-h2 yet?

Hi Jay,


In working with TAC, we'll be loading 11.0.3-h10 tonight during our maintenance window to see if it helps with the HA2 links crashing.  Fingers crossed.  🙂
