Freezing after 40 minutes

Overview

I set up pihole on a pi 3b +. I used the current 64bit lite version of the raspberrian os and flashed a sd card with the image. Then I installed pihole and imported settings with the teleporter. I opted to only import the lists, and not the other stuff like clients, audit logs, etc

The pi has unbound installed as the recursive DNS server, and pfsense hands out the IP of the pi to clients

I noticed in the log there was this, but I am not sure if it is relevant.

*** [ DIAGNOSING ]: contents of /etc/lighttpd/conf.d
/etc/lighttpd/conf.d does not exist.

After boothing the pi, pihole runs fine for 40 minutes or so and then completely fails to respond. I also couldn't ssh into the pi either. I am not sure what the issue is, but I was wondering if someone could help.

Expected Behaviour:

Pihole runs without freezing

Actual Behaviour:

Freezes after 40 minutes

Debug Token:

This is normal in Debian and Ubuntu operating systems.

The fact that SSH breaks as well indicates that this isn't a pihole issue as much as possibly hardware or SD card related. Possibly even a poor / faulty powersupply.

You may wish to go through the logs ( journalctl ) and see if anything shows up there. If your unlcear on journalctl this article is a good start.

You could also just keep journalctl running on the ssh session, dumping its output to the terminal and wait for the crash if it happens that often you may catch something realtime ( sudo journalctl -f ).

Some quick particulars to look for.

Under voltage:

sudo journalctl --full --dmesg --grep voltage

Out Of Memory:

sudo journalctl --full --grep oom

Anything critical + warnings:

sudo journalctl --full --catalog --priority emerg..warning

Okay thank you. I will check these out and see what is going on.

Here is what I am seeing:

for sudo journalctl --full --dmesg --grep voltage

-- No entries --

sudo journalctl --full --grep oom

I dont know what time it froze.
But thats where you need to focus.

From that "timed out" error above, it could be network related.
But you might have better luck on the Raspi forums as I dont see any evidence Pi-hole is causing this.
At least not from the journal.

Okay thank you. I tried re configuring the pihole with pihole -r based on another thread I found. If that doesn't help I think it's safe to say this isn't related to pihole anways. Appreciate your help regardless
