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

L1 Bithead

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

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

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.
