When the ESA connects to our AD servers there are errors 4625 and 4768 listed in the Event log.  The ESA is displaying that it was successful.

I have a WLC 5508 that loses connectivity to all of the AP's on it.  Running version 8.0.140 with 52 Access Points.  I have to reboot the controller to get connectivity working.  

Getting a high amount of CRC errors on both 5ghz radios.  Is this from poor antenna alignment or interference?
