Error message: "dnsproxy: exited, Core: True," followed by system restart when accessing ACC or Monitor tab

• When accessing ACC or Monitor tab, the dnsproxy proces crashes multiple times followed by device restart.
• Following "system log" messages are seen before device restarts:

2022/09/22 00:24:55 high     general        general 0  dnsproxy: exited, Core: True, Exit signal: SIGABRT

• This happens when  DNS server is not configured on the firewall and accessing ACC tab, or Monitor tab with enabling "resolve hostname".

• Any Palo Alto Firewall
• PAN-OS 9.1.15, 9.1.16, 10.1.6, 10.1.7, 10.1.8, 10.2.2, and 10.2.3
• DNS server setting not configured

• When accessing ACC tab, the firewall tries to resolve an IP address to a hostname with using DNS lookup.
• When enabling "Resolve hostname" under each logs (Monitor > Traffic, Threat and etc), the firewall tries to resolve an IP address to a hostname with using DNS lookup.
• Since the system does not have any DNS server settings under Device > Setup > Services, it will fail and process crashes and ultimately the device restarts.

1. Workaround: Adding a DNS server setting under Device > Setup > Services. Even adding a dummy IP address resolves the issue.
2. Fix:  Fix is released as PAN-198174 (fixed in 10.1.9 and 10.2.4)
