Octoprint 1.8.1 hangs on Octopi

What is the problem?

Since updating to Octoprint 1.8.0 and now 1.8.1 Octoprint hangs or crashes completely after some time sporadically. Needs power on reset on Raspberry Pi Zero 2 W to solve it (but also after restart sometimes the Octoprint service hangs with 100% CPU load making the Raspi unaccessible over the network / cannot even ping it)

The issue occurred 1st time after updating to 1.8.0 and doing a print, at the end of the print (5-6h) Octoprint was no longer reachable on the network so I restarted the Raspi.

After updating to 1.8.1 initially there were no issues, but now Octoprint / the raspberrypi is not reachable at all most of the time (only by chance I can login into the console). However when I do it I can see Octoprint utilizing 100% CPU all the time. Only thing that happens is that my LED stripe gets turned on by Octoprint.

What did you already try to solve it?

Reboot, Restart

Have you tried running in safe mode?

Not possible since Octoprint currently does not startup or stops hanging

Did running in safe mode solve the problem?

Same here with Octopi 1.8.1 & Raspberry Pi 3B+. Please help !. Thank you very much.

Hello you two!

Please try safe mode (<- click me). You can start OctoPrint in safe mode via SSH.
You can find information on this in the safe mode link.

I did not even know how to start OctoPrint in safe mode. Thanks for giving the link to this documentation.

Hello @kinife !

Not quite.

  1. You are running on Klipper.
  2. Klipper can connect to the printer, but the printer reports an issue. Maybe an issue in the printer.cfg.

You may get better help in the Klipper forums: https://klipper.discourse.group/
