HIGH CPU on 4510 after 802.1x

I put a customer on 802.1x using 4510. The CPU went up and trying to troubleshoot why. I have a similar setup some place else and everyhting is normal. Any ideas??

Did you notice any memory allocation error along with below listed error message in traceback

CHKPT-3-NOMEM: Unable to allocate resources for CF on (Get buffer failed).

If yes, then please review the symptoms of this defect. This is the most closest defect I could find.
