Do you mean you're running a Pylons web service in Jython, and having another Python process start it up via subprocess? If so I'm not sure why sending the subprocess a kill/terminate signal would cause it to dangle, it could depend on what the parent process is doing. You may need to pass close_fds=True to Popen. Can you kill it normally when it's ran outside of your other process? A web service call to shutdown Pylons via sys.exit could work, but I'd want to know why the process was dangling when killed. It may even zombie after calling sys.exit() on itself due to the same issue. -- Philip Jenvey -- You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
