Expected Behaviour:
I upgraded my two PiHoles last night, the backup looks to be ok and stable, the primary required much more handholding to get it back into a reasonable state. What is happening in the primary unit goes unresponsive, where there are delays navigating between pages, or DNS resolution locks up for about 10 sec and my clients cannot access things on the Internet.
I notice that the primary CPU is higher (~25%) than the backup (~10%), and this is true when I failover to the backup to service my home network. I run keepalived for HA
These are both Running on Pi 4
