Sophos UTM 9.510-4 released - let's share experiences!

Seeing a ton of these messages every few seconds in the DNS proxy log.

No idea where to even look to resolve this...?   Don't see these messages in the previous logs, only after updating to 9.510-4.

UPDATE:

This flood of messages occurs when dns forwarding is configured (network services/dns/forwarders). Doesn't matter what goes in there, google, cloudflare, opendns, etc.  All cause these messages to be generated multiple times a minute. Happens regardless if "Use forwarders assigned by ISP" is checked ornot.

UPDATE 2:

Set up a test utm installation. Using ssh to do nslookups directly from the utm.  Every time a dns lookup is initiated (ping, nslookup), the resolver priming query line below is generated in the log if a dns forwarder is configured.  This is reproducible on the main utm too.

So to keep the flood of these from filling up the dns proxy log, nothing on the dns forwarding screen needs to be configured or checked.

Hello,

I can confirm the "resolver priming query complete" flood in DNS-Proxy-Log. Fills up quite fast. Is there a way to switch the parameters back from the now "verbose" configuration?

Thanks for the update.  I won't even think about upgrading til sometime in october.  This issue indeed sounds like excessive logging was enabled for some reason but never turned back off.  Maybe fixed in the next update¿?
