A good way to use supervisor2 is to write a shell script that you know starts your application, and then give that to supervisor2. If you do, be sure you do "exec paster ...", as this replaces the shell process with the paster process, and signals will be properly sent from supervisord to paster. > I suspect the problem was needing to set the PATH and PYTHONPATH to > match my workingenv.

The console (Gentoo) says: Are you using trunk? I think this bug was fixed there. -- Ian Bicking | [EMAIL PROTECTED] | http://blog.ianbicking.org | Write code, do good | http://topp.openplans.org/careers --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
