Octoprint Crashing Intermittently - Has Log Errors

What is the problem?

Octopi server fails intermittently over varying amounts of time. Sometimes it will fail a an hour or so in, other times, after many hours. When it fails, I am no longer able to use the web interface and ssh fails. It locks up with the printer head at the last position before failing Hotend and bed stay at the set temp.

I have a ton of log errors and am hoping someone may see something since I don't know what I am looking at.

Log errors... (I trimmed the lines to get a count of the error types - full lines in sysinfo)

What did you already try to solve it?

  • Reboot and try again, somethines works.
  • Changed to a shorter 3' cable with ferrite bead (Amazon.com)
  • Checked the power supply for proper amperage
  • Verified camera is properly attached
  • Reduced camera resolution to avoid bus overload
  • Added UPS to prevent possibility of brown outs
  • Am picking up a new SD (Amazon.com) to reimage the server (don't want to lose my current setup if this is not the problem)

Have you tried running in safe mode?

Trying again now

Did running in safe mode solve the problem?

Will know in the morning.

Hi djr,

my two cents worth, a quick skim through your logs look to me like a webcam related problem that I also experienced recently, however I did get error messages in red on the screen stating that the voltages are too low often. The webcam I used was quite power hungry, especially at high resolution and high frame rates.

The proxy logs also show your system hanging after issuing a webcam command, so it might be worth testing without a web cam by unplugging the webcam and setting the streaming to disabled.
