First off thanks so much for compiling unbound into docker for the raspberry pi. I have just recently learned about unbound and I have been experimenting with it and PiHole running together in a docker container. I have everything working and I can definitely tell a difference in speed with my DNS queries. But when I look at the logs for unbound, I am seeing a large amount of DNS queries going to cloudflare.com. These queries are occuring once every second which seems high:

I do not know if this is supposed to be normal behavior, such as a keep-alive. I checked PiHole DNS query log and didn't see anything that was similiar. For the Unbound Config file, I am just using the standard config file with no alterations. I am using encrypted DNS settings ( port 853 ) out to cloudflare:

Can you kindly verify if this action is typical and supposed to be occurring.
Please see below for an example of my docker-compose file:
