Hello!
I'm running the majority of your stack, but seem to be having an issue with Monerod utilizing too much CPU. For the first 10 hours it runs, it's completely fine and doesn't use more than 4-8% of CPU. (This is after sync, 100%, and running a full node).

After the 10 hours, I get a sharp intake to pretty much a constant 180% CPU usage (4 core, 8GB RAM VPS). I'm not quite sure what's going on? It will stay like this until I restart monerod. Once I restart, it will be okay again for another 10-12 hours, and then it goes into the same pattern. Any help would be appreciated. I can post whatever logs you may require.

Cheers

@NeonMinnen please post logs from monerod when that happens, would be helpful! If the standard level of logging is insufficient we can increase it as well.

Also please post the exact Docker Compose snippet you're using for monerod if different in any way from the one in the repo.

@sethforprivacy Hi! Sure thing.

Here is the compose snippet.

monerod:
    image: sethsimmons/simple-monerod:latest
    restart: unless-stopped
    container_name: monerod
    volumes:
      - /mnt/volume-1/bitmonero:/home/monero/.bitmonero
    ports:
      - 18080:18080
      - 18089:18089
    command: >-
      --rpc-restricted-bind-ip=0.0.0.0
      --rpc-restricted-bind-port=18089
      --public-node
      --no-igd
      --no-zmq
      --enable-dns-blocklist
      --limit-rate-up 100000
      --limit-rate-down 100000

Here is also an image of the normal CPU usage to the left, versus when it goes into full CPU hog mode. Taken directly from the monerod CPU usage via Netdata.

Here are some logs that look concerning. I couldn't find anything in between when it actually happened, it seemed to stop logging.

Not sure if anything in here is helpful. I believe this is log_level <1>. I've restarted the container and everything is normal. I'm expecting the same thing to happen again in 10 hours, so I've enabled log_level <2> to get some more logs to post next time it happens.

Thanks for the details!

Only thing that is odd is the stack trace -- do you see that everytime CPU spikes?

The only other thing you could try is removing --public-node from the command args to stop advertising your node publicly and see if that reduces it, but your config of course is normal. If this was a widespread issue I'd be surprised to not have heard from anyone else on this.

It's strange. When it is doing it's CPU hog thing, it literally is like pinned at 50-55% it doesn't really spike perse.

I really want to run a public node. I don't remember having these issues with the pruned setting, and not running the actual data directory for the blockchain on a hetzner volume. I'm re-syncing a pruned node from scratch, set log level to 2 and going to see if I have the issue after it's done syncing.

Would having the volume on another disk be an issue? I didn't think it would at all. I'm using a volume from Hetzner cloud, as I wanted to run a full node and not take my whole VPS root space up.
