The issue I am facing:
I installed pihole on an orange pi zero 3. It worked great for months. About a month ago it would become absolutely unresponsive even over ssh. Thinking maybe it was a hardware issue I spun up an LXC on my proxmox server and teleported over all my settings. I reinstalled the OS (armbian ubuntu server), used a different SD card and different OPZ3 board I had. Fresh install of phole with only my local CNAME and DHCP leases passed over manually, but the whole systems would still become unresponsive after some time (Although I do think it seemed to last longer, but that might be because some devices hadn't moved over to update DNS setting.) I switch it back to the LXC and checked on it and noticed that it was saying it was having a very heavy load.
This LXC has 6 cores of a retired enterprise server (nothing new just an HPz820), but its still complaining that the load is too much for the number of cores. So I'm guessing that is what is overwhelming the little OPZ3. But I can't figure out what is causing that issue. ntop, proxmox lxc summary, and other monitoring tools are not showing that much usage on the it. Is there any way to tell what is killing the OPZ3 when it compelty becombes unresponsive after a few minutes? I'm uploading the debug response for the LXC instance since that is the only one I can get at.
Details about my system:
originally Orange pi zero 3, moved to Proxmox LXC with 6 cores from a Xeon E5-2667 v2, 2GB ram. https://tricorder.pi-hole.net/UDbSpIyi/
What I have changed since installing Pi-hole:
Tried an instance that was as close to factory as I can get except for the CNAME list and DHCP Static leases. My other instances has a lot of non-standard setting becuase I've messed with stuff a lot trying to troubleshoot everyso often.
