File Sharing Service Stops


This is pretty basic, but can't figure it out. I have a server in my house, running the latest Mountain Lion Server. I have it set up to do file sharing and it works like a treat at first. But without fail the file sharing service cuts out and I have to remote login, and re-open the server app. I can't figure out why its closing, and even if that app closes, the file sharing is supposed to still be running as a service, correct?

The rest of the server is running fine. SickBeard, SABNzbd+, and couchpotato are going nonstop. And Plex clients are never interrupted. I'm sure the problem lies within the itself but I can't figure out why it keeps going in and out. googled to no avail.
