Hey Pete, So my system has been up for 1 1/2 days. I came home today and shutdown the server to start adding hardware back in one at a time. I had pulled 2x2GB dimms out and my cache, and controller card that it attached to. I have installed the controller card with out cache attached and powered back on. I will add the cache back tomorrow. I will continue to post daily until I determine the cause. Check out a post from WillDouglas. He is having similar issues and has not determined the root cause yet.
