[BUG] Scalene can't generate the final JSON output

[agemagician]

Describe the bug I am trying to debug a python script, but it crashes during the profile generation step.

To Reproduce Steps to reproduce the behavior: python -m scalene --cli --reduced-profile --profile-interval 180 --profile-all --outfile scalene-profile.txt --memory-leak-detector myapp.py & or python -m scalene --cli --reduced-profile --profile-interval 180 --profile-all --outfile scalene-profile.txt --memory-leak-detector myapp.py Unfortunately, the code is a company code and I can’t share it.

Expected behavior When I run the profiler, I can see the program started to produce and update the "scalene-profile.txt" every 180 seconds, but after it finishes and started to write the final JSON file it crashes.

Screenshots without using the final "&" at the command line profiler:

• Version 20.04

Additional context I have checked the code and the problem seems to occur after the program finish and starts to write the final JSON file. I can also see that the profiler is working correctly because it is generating the intermediate output.

I have used another machine and now it is working. I am not sure about the reason, but maybe it is related to sudo privilege, and the location that logs are stored.
