If the device is unable to resolve any of the listed domains within the logs, one would expect these logs to be generated within the System logs.

So diving a bit deeper:

This is slightly confusing as the 'type' of dnsproxy would indicate to many that you are using the actual dnsproxy feature on the firewall, but this isn't the case. There is a object by default called mgmt-obj that works to resolve hostnames when you check on the "resolve hostname" checkbox in the various logs, or if you utilize that feature during a scheduled job. This trigers a reverse dns lookup using the arpa database, and sends a dns query for a pointer record of the domain name. 

If this process fails for any reason you would see the indicated logs; many people have noticied it with 8.1 in particular.
