Clearpass I/O spikes and increase over time


We have observed behavior in our vmware clearpass server that is abnormal, and does not seem to be rectified by moving to a newer version.  The read rate, both in IO and in disk rate, spikes repeatedly, and over time gets progressively higher until the system must be restarted to temporarily solve the issue.  Currently it takes a month before requiring a reboot, but the problems occur long before that.  It has more than enough IO to spare on the SAN, has been given its own datastore and resources, and appears to be every requirement, but somewhere along the way either something is misconfigured or there is a memory leak of sorts.  I have attached several screenshots showing the problem, both from our vmware server's as well as our Nimble SAN's POV.  


What places should I look into next to remedy this behavior?
