[chef] Re: Re: knife ssh not keeping the process live

It's unclear from your post whether those steps are being called from Chef via a script which performs them, or directly via Chef (ie, multiple execute blocks). If it's the latter, I would suggest externalizing it into a script and having Chef execute that.

You're assuming that tomcat is daemonizing but it seems the task is running with some option that prevents it from forking and leaving the current shell (so it's parent ID process is init)

Check startup.sh and make sure the command is run without debug or "no fork" or whatever equivalent option tomcat uses. It might be as simple as "write output to stdout" and when your shell exits the task dies. (broken pipe)

Hope that helps
