What does 247 exit code mean?

Hey,

I'm running pants 2.15.0 to run a set of unittest cases but I keep getting this error only when running the code with pants. When I run the test cases locally with pytest they succeed.

✕ <dir>/<dir>/test_<name>.py:test failed in 1280.49s.


Process exited with code 247

What does this mean? How can I address it?

What platform are you on? How are you running tests with pants vs without (eg multiple tests at once, or just a single file)?

Some web searching gave a hint that this might be an out of memory error in some form, which might be easier to trigger with pants since it runs several files in parallel, by default.

It's being run in teamcity inside a docker container. Pants is executing pytest on a single python file. I also saw online someone say it could be a memory issue so we set the pantsd-max-mem flag to something very high, but it still gave the same error. We also tried the --oom-kill-disable flag on the docker container command but had no luck there either. I'm not sure it is actually a memory issue

I suspect the pants memory limit isn't the cause of issues here, as, I believe, that's just a limit on how much memory pants itself will use, rather than a limit on the tasks/processes it spawns.

Do the tests run with pytest alone (no pants) on CI? Does the docker container itself have memory limits?
