ISE 1.2 - WLC 5508 - NAS sends RADIUS accounting update messages too frequently

I'm getting this error in ISE referring to my Cisco 5508 WLC.  I'm not sure how to turn down the frequency.  Any ideas?

Verify NAS configuration. Verify known NAS issues.

I opened up a TAC case with Cisco yesterday and this is the response i got from them:
There is bug on the WLC side to reduce the number acct updates:
CSCug14713- WLC sends acct-update twice in the same millisecond
This is fixed in 8.x on the WLC.
So, it looks at though we just have to deal with it until they release an 8.x version for the WLC. In the meantime, you can disable the alerts in ISE.
Administration>Settings>Alarm Settings>Misconfigured Network Device Detected
Edit that alarm and set it to disabled
