What is the problem?
I have had two failed prints now in a row where the Prusa is showing M112, Emergency Stop.
Same .gcode file and both stopped at the same spot after about 7-8hours of printing. Have been printing similar files for the last 2 weeks with no issues.
On reviewing the Octoprint.log both times before the M112 was called the printer and octoprint looped with the following. (3 sets with 5 times of each occurrence)

I cant see anything myself in the Gcode that stands out, and both failures happened on the same layer.
I am printing now in Safe Mode to see if it prints, if it fails I will reslice the models and print again.
The print is for a bed full of tokens about 35mm diameter and 5mm high. I have printed 100's in the last few week with no issues until this set.
Thought I would ask the community for other options to look at while I wait the 7 hours to see if it fails again or not.
What did you already try to solve it?
Restarted Printer, Restarted Octoprint - Full power down of both.
Started Reviewing logs and Gcode. enabled Serial logging
Trying same Gcode in Safe Mode now - if fails again will try reslicing parts and printing again.

Have you tried running in safe mode?
Running print in safe mode now
Did running in safe mode solve the problem?
Waiting for results
