When we run a SauceConnect job, it leaves the process running so the PID file is never removed.

The next job tries to run and gets the error message "Error creating pidfile /tmp/sc_client.pid: resource temporarily unavailable"

I can manually kill the process, remove the sc_client.pid file, then start the job and it runs with no issues.

At the end of the job that runs correctly, there is a java error, but I'm not sure if it is related or not.

I have added the sc.log to the ticket from the master node.
