Firewall random reboots cause of critical error dnsproxy: restarts exhausted, rebooting system

[FarkhanAliyev]

Hey dear colleagues!

Our customer faced an issue when firewall starts to randomly reboot without any reason. We requested a TSF and in even analyses we found that customer had Split Brain and this two errors:

dnsproxy restarted unexpectedly however no known issue was identified. Please open a case if further assistance is required.

dnsproxy: restarts exhausted, rebooting system
 

I couldn’t find any information about this issue and still wondering what can cause this issue. DNSproxy is not configured on the device.

PAN-OS v. 10.2.2
Model 3220

Hello,

I would recommend opening a support case. However for the split-brain, change the priorities on the HA config in the 'Election Settings'.

@FarkhanAliyev,

The moment you have an FQDN address object you are using the DNS Proxy service from a device aspect. With that in mind, I would guess that you actually are using the process itself. Not that this really fixes your issue, you still need to open a case to address root cause.

You could take a look at the actual dnsproxyd.log file to see if it actually logs anything that might point towards the problem as you work through the issue with support.

Thank you dear colleagues for your help!

Did you find a solution for the problem?

Yes, solution is to configure DNS server on Device>Setup>Service. This is a bug. Lack of this setting shouldnt cause firewall to reboot.

I had the same issue. I put a DNS server on the field. I would like to know if it's a official bug or if you've opened a Tac what was the RC
