Sorry for the issues you are seeing. We are recently encountering a few bugs we have not anticipated due to missing kernel features/ancient kernels. Let's find out if you are affected by the same issue. If so, we already have a fix for this.

Can you reproduce the crash (I guess so). If so, can you please follow the steps described on https://docs.pi-hole.net/ftldns/gdb/ and come back with the backtrace info? I will probably lead to the solution right away once we know where to look

#2316 the same issue, I'm added my report there.

I'm away from home for a couple of nights, and pihole had been running nearly 24 hours so far.
