CAPWAP-3-CAPWAP_PAYLOAD_TOO_LARGE

Any ideas what this means?

These are 1100s in light-weight mode, managed by 5500WLC or WiSMs running 7.0.116  Message appears sporadically, every few weeks, sometimes once in a day, sometimes in bursts, typically from a single AP (out of a flock of ~200 campus-wide), the APs involved tend to live within a particular cluster of buildings.

You might as well open a TAC case on this unless one ot the Cisco guy's here can lookup that message.  That message is not in the guide for that code you show:

Are the affected AP heavily loaded with voice and data clients.

Matching Bud ID - CSCtc82074

However the bug is fixed on 7.0.98.0 and it stops AP from crashing after this error message.

Printing error msg and traceback is ok but the AP shouldn't crash.
