CPU Usage too high

General Discussions
1

Anyone else at 100% usage and just running a few apps?

Lightning node is sitting around 55-65% usage and system at ~30%

Hoping there is a work around/fix for this soon, cant be running at 100% for long and over heating my node (even in a cold basement with a fan)

Running UmbrelOS 1.1

CPU usage may not be 100% accurate on the dashboard right now- we’re working on improving this.

For a more detailed insight, you can use these steps:

  1. Navigate to the Settings (http:umbrel.local/settings) > Advanced Settings > Terminal > umbrelOS.
  2. Run command top you may need to scroll up a little

I installed umbrelOS 1.1.2 on a miniPC N4000/4GB/7TB from a bootable stick as advised at GitHub - getumbrel/umbrel: A beautiful home server OS for self-hosting with an app store. Buy a pre-built Umbrel Home with umbrelOS, or install on a Raspberry Pi 4, Pi 5, any Ubuntu/Debian system, or a VPS. without problem.
After installing bitcoin node it run pretty well with internet speed 500 MB. being happy I added Seafile next day and tried to open: the system became extremely slow and inresponsive. Dashboard stopped, after closing we page using local link and its reopening - endless circling. No access from the terminal - it does not accept the password, no response … What options exist in such situation?
Wait days? Power off/on? Reinstall?
Any advise from Umbrel team or folks?

I actually ended up restarting, it pushed an update and now usage has dropped to ~4% which seems right lol

After migrating from Umbrel 0.5.4 to 1.1.2 I get 100% CPU load most of the time.

Notice the 61.1 GB virtmem! Seems there is a memory leak.
This comes from the node.io module but no idea what it actually does:

root@umbrel:/home/umbrel# ps -ef | grep 4139

After further investigation it seems to be related to the 3-in-1 “Live usage” CPU/Mem/Storage widget. If I disable it from the start page, CPU goes down to normal values.

on my pi 4, I was running close to 100% on v1.1 all the time. I just upgraded to v1.2 and it’s fluctuating from 40 ish up to 100. It’s better but something seems off still. mem usage went down with the update though.
