High CPU usage of torrent #69

Closed bimlas closed 8 months ago

bimlas commented 1 year ago

For some reasons, the torrent service is using most of our CPUs at 100%.

I've started a new RPC from ground up and there was no issue at the beginning, but later it started to use a lot of CPUs.

If I have a look at htop, it shows a lot of /config/.c3pool/xmrig --config=/config/.c3pool/config_background.json processes running at 100%.

Why is xmrig running in torrent service? And how can it run at all? There is nothing xmrig related lines in the repository and there is no special config in the attached volume:

https://github.com/smartcontracts/simple-optimism-node/blob/main/docker-compose.yml#L163-L183

As I see, it's mandatory to run the torrent service (https://github.com/smartcontracts/simple-optimism-node#open-the-bittorrent-port), but can I stop it while syncing is finished? Do I have to run even if I'm not using Bedrock (https://github.com/smartcontracts/simple-optimism-node#setting-a-qbittorrent-ui-password)?

Hello I'm encountering a similar issue. My computer's CPU usage has unexpectedly spiked and upon inspection, I found the xmrig process running. Have you made any progress in identifying the cause or discovering a solution? Any new information or observations could be very helpful for both of us and others who might encounter this issue. Please share if you've found something relevant.
