PA-3420 sudden restart issue

L1 Bithead

Hi all,

One of our clients has a PA-3420 HA-pair device with an active-passive setup, one day they noticed that their firewall went to reboot. Upon checking there are no signs on the system logs that encountered power interruption or hardware failures, we checked on using PANTS and the Auto assistant tool, but we did not find any event that pointed us to the cause of the firewall reboot.

We are also seeing this warning on the auto assistance.



Could anyone help me how I can figure out the cause of the firewall to reboot?

There's nothing in the logs you've shared which will help provide a definitive reason.  You're more than likely going to need a support case to find the root cause.


There are a lot of platform stability issues with the 10.2 code, especially with the 3400 code base.  Not sure what code these 3420s are running but it's possible the HA reboot happened because of a known bug that's mitigated in a later release.
