Hey John. We had the same problem with extremely low load. Some form of leak. Never found a good solution (besides reboot when leak reaches critical as a work around). For the exact same purpose (code/file transfers) running on Ubuntu 14.04 is much better. I recommend you upgrade unless you can fix it yourself. Seldom admins pick up these older bugs.
