i guess this example is incomplete... please give a full example or we can't help. you've to call self.SpringPID.wait() and not terminate() this looks like a zombie process: http://en.wikipedia.org/wiki/Zombie_process you've to read the return value to make it disappear. when reading the python docu, terminate() doesn't read the return value... http://docs.python.org/library/subprocess.html this works: import subprocess import time proc=subprocess.Popen('/home/abma/local/spring/master/bin/spring-headless') proc.terminate() proc.wait() time.sleep(1000) |
