• If it's IIS, there are a couple things that we have run into. 
    If there is any 32 bit code, IIS can't address memory.  Re-starting it worked.  Getting rid of the 32 bit code worked better!
    Re-cycling the app pools may also need to be looked at. Depending upon the connections, when a recycle occurred, CPU went through the roof.
