----------------------------------

             Summary: "/bin/bash: bad interpreter: Text file busy": VanillaSoftwareProcess fails to execute commands
                 Key: BROOKLYN-294
                 URL: https://issues.apache.org/jira/browse/BROOKLYN-294
             Project: Brooklyn
          Issue Type: Improvement
    Affects Versions: 0.9.0
            Reporter: Aled Sage


When deploying an app to an OpenStack environment (behind a VPN), one of the VanillaSoftwareProcess entities failed to execute "customize" with the error shown below:

{noformat}
-bash: /tmp/brooklyn-20160608-111535279-hYmg-customizing_VanillaSoftwarePro.sh: /bin/bash: bad interpreter: Text file busy
{noformat}

This error means that another process is accessing the file (i.e. has some kind of lock on it), so we can't execute it.

Just before this, the first attempt to upload the script failed after approx one minute timeout. I'm guessing that the VPN went down temporarily while it was trying to upload the script.

I'd have expected that the failed upload would not have kept a lock on the file, but that seems to be the most likely cause based on the log snippets below:
