The error appears in the file specified for the stderr output of the DaemonContext. Here it is without the unwanted extra line-wrapping that seems to plague all Google Mail users (seriously, folks: get a real mail provider that won't mangle your messages):: Traceback (most recent call last): File "/home/bignose/Projects/python/python-daemon/bin/andy-clegg-test", line 7, in <module> subprocess.Popen(['echo', '1']).wait() File "/usr/lib/python2.5/subprocess.py", line 1184, in wait pid, sts = self._waitpid_no_intr(self.pid, 0) File "/usr/lib/python2.5/subprocess.py", line 1014, in _waitpid_no_intr return os.waitpid(pid, options) OSError: [Errno 10] No child processes I confirm that I'm getting the same error; Python 2.5.4. My first thought was perhaps it's related to the fact that the process has no stdout? But setting ‘stdout’ and ‘stderr’ to the same file:: #! /usr/bin/python import daemon import subprocess fake_console = open("fake_console.txt", "w+") daemon.DaemonContext(stdout=fake_console, stderr=fake_console).open() subprocess.Popen(['echo', '1']).wait() still gives the same error:: 1 Traceback (most recent call last): File "/home/bignose/Projects/python/python-daemon/bin/andy-clegg-test", line 8, in <module> subprocess.Popen(['echo', '1']).wait() File "/usr/lib/python2.5/subprocess.py", line 1184, in wait pid, sts = self._waitpid_no_intr(self.pid, 0) File "/usr/lib/python2.5/subprocess.py", line 1014, in _waitpid_no_intr return os.waitpid(pid, options) OSError: [Errno 10] No child processes I'm not familiar enough with the nuances of the ‘subprocess’ module to know what might be going wrong here. I'd like to know whether it might be a problem in the ‘python-daemon’ library. -- \ “Whatever a man prays for, he prays for a miracle.
