Could not open up the PID on a DNS only server

While I was restarting LFD, I noticed that I could not open up the PID on a DNS only server. The CSF is giving me the PID file error (cannot open it) even when I updated the CSF to ver. 13.08 on CPanel. The PID file does not go away by itself, which is even more puzzling. Thoughts? I have duplicated it on 2x Webmin servers too, my full CPanel works fine though.
