DNSMasq SEGTERM and Pi-hole web interface freezes

spyentist · November 19, 2022, 2:20am

Expected Behaviour:
I am expecting pi-hole to work normally as it has for the past few months.

Raspberry Pi OS

Raspberry Pi 0 w

Actual Behaviour:
DNSMasq will receive a SIGTERM request and the process will die and not restart. Today the web interface did not freeze so I was able to restart it but it has happened 3 times today and 5-10 times in the last week.

Debug Token:
