Ya, I figured it was the NAS. All the reading I did seemed to suggest that.

I was able to force the 2960 to sent at regular intervals by setting the Acct-Interim-Interval option in the Accept-Request packet. But that didn't work for the WLC.

The NAS originates accounting packets. If it's not originating
accounting packets, blame the NAS.

This is a common theme with RADIUS. FreeRADIUS isn't perfect, but
when things go wrong, blaming the NAS and/or the SQL server is a pretty
good decision.
