[c-nsp] 3750 integrated WLC keepalive problem

[Brian]

I'm starting to wonder if this is a compatibility issue with the switch
IOS.  The release notes for 12.2(44)SE only mention compatibility for WLC
version 4.1.x.  This seems hard to believe.  Does anyone have a 3750 WLC
with version 4.2 or later?
