I'm trying to run a

job

consisting of a series of

op

but I keep getting the following error:

dagster._core.executor.child_process_executor.ChildProcessCrashException

Stack Trace:
  File "D:\Documents\GitHub\mycelium\venv\lib\site-packages\dagster\_core\executor\multiprocess.py", line 240, in execute
    event_or_none = next(step_iter)

    raise ChildProcessCrashException(exit_code=process.exitcode)

Why is this?

Does it say what the exit code was in the error message? This means that the code in your op crashed the Python process that was running it. This can happen for a variety of reasons depending on the code being run, but the most common one we see is the process running out of memory.

Thanks, one of the lines were failing silently - it's all solved now.
