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. See https://chromium.googlesource.com/infra/luci/luci-py.git/+/master/appengine/swarming/doc/Bot.md#Graceful-termination_aka-the-SIGTERM-and-SIGKILL-dance for more information. *** May the SIGKILL force be with you *** 2019-03-25 14:22:55,502 - root: [DEBUG] Contents of task_output_dir: ['c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v\\43cf7ef11f397410'] 2019-03-25 14:22:55,503 - root: [WARNING] Expected output.json file missing: set(['c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v\\43cf7ef11f397410\\output.json']) Found: [] Expected: ['c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v\\43cf7ef11f397410\\output.json'] 2019-03-25 14:22:55,503 - root: [WARNING] No shard json files found in task_output_dir: 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v' Found ['c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v\\43cf7ef11f397410'] 2019-03-25 14:22:55,503 - root: [DEBUG] Found shard_json_files: ['c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v\\43cf7ef11f397410\\output.json'] 2019-03-25 14:22:55,503 - root: [INFO] merge_cmd: C:\b\s\w\ir\cache\vpython\691c07\Scripts\python.exe C:\b\s\w\ir\kitchen-checkout\build\scripts\slave\recipe_modules\chromium_swarming\resources\noop_merge.py --summary-json c:\b\s\w\ir\tmp\t\tmpkk6rey.json --task-output-dir c:\b\s\w\ir\tmp\t\tmpdvqs9v -o c:\b\s\w\ir\tmp\t\tmpgbayuq.json Running ['C:\\b\\s\\w\\ir\\cache\\vpython\\691c07\\Scripts\\python.exe', 'C:\\b\\s\\w\\ir\\kitchen-checkout\\build\\scripts\\slave\\recipe_modules\\chromium_swarming\\resources\\noop_merge.py', '--summary-json', 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpkk6rey.json', '--task-output-dir', 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v', '-o', 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpgbayuq.json'] in None (env: None) Command ['C:\\b\\s\\w\\ir\\cache\\vpython\\691c07\\Scripts\\python.exe', 'C:\\b\\s\\w\\ir\\kitchen-checkout\\build\\scripts\\slave\\recipe_modules\\chromium_swarming\\resources\\noop_merge.py', '--summary-json', 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpkk6rey.json', '--task-output-dir', 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpdvqs9v', '-o', 'c:\\b\\s\\w\\ir\\tmp\\t\\tmpgbayuq.json'] returned exit code 0
