      Original description

      Hi guys!

      I'm trying to start mongod process from python script, using subprocess module, and this is what mongod crashes with:

      about to fork child process, waiting until server is ready for connections.

      ERROR: child process failed, exited with error number 14 <err>:  <args>: ('/usr/bin/sudo', '-u', 'mongodb', 'mongod', '--fork', '--config=/etc/mongodb.shardsrv.conf', '-vv')

      I've tried all combinations of arguments and subprocess flags, and i still getting the same error. If i run mongod with the same args from shell - it starts, and i don't get no errors.

      It worked with previous versions of mongo (2.0, 2.2), but it doesn't in 2.4.
