Description

Running contest's tool sometimes resets several class generation executions. It is not very clear what exactly happens but looks like that instrumented process is dying and sends through log some "null" states to the runner. The latest processes these nulls as a command to stop and rerun the contest tool itself.

To Reproduce

Run the contest tool from the docker.

Expected behavior

Every class generation process should be processed without restarting.

Actual behavior

Some generations are restarted.

Additional context

ContestKt tool.
