You don't want to leave children processes outliving the task on the Swarming bot, do you? The Swarming bot doesn't. How to fix? - For any process that starts children processes, make sure all children processes terminated properly before each parent process exits. This is especially important in very deep process trees. - This must be done properly both in normal successful task and in case of task failure. Cleanup is very important. - The Swarming bot sends a SIGTERM in case of timeout. - You have 30.0 seconds to comply after the signal was sent to the process before the process is forcibly killed. - To achieve not leaking children processes in case of signals on timeout, you MUST handle signals in each executable / python script and propagate them to children processes. - When your test script (python or binary) receives a signal like SIGTERM or CTRL_BREAK_EVENT on Windows), send it to all children processes and wait for them to terminate before quitting.
