[c-nsp] 3750 integrated WLC keepalive problem

[Brian]

Hello,

I have a couple of 3750 integrated WLC's that are continually rebooting
themselves.  I was able to configure the controller and each are on version
4.2.130.  3750's are on version 12.2(44)SE2.  When doing a debug platform
wireless-controller, I see the following:

22:27:01: WRLS: Missed keepalive src 127.0.1.1 missed 1
22:27:07: wcp-tx: src/dst:127.0.20.20/127.0.1.1 ver:1 sap2/1
22:27:07: typ:req len:61 seq:3816 flg:0 sts:1
22:27:07: 00 00 00 01 00 00 00 18 00 00 00 04 7F 00 14 14
22:27:07: 00 00 20 00 01 3B 04 BB 1F 49 45 50 46 44 46 41

After 15 misses, it sends a reset and reboots.  I believe this has to do
with the service-port interface on the controller.  Is it an requirement
that this interface is routable?  When issuing a show platform
wireless-controller, I see it assigns service VLAN 4095 and
127.0.1.1address.  I just have a dummy address configured on the
Controller and I
tried to configure it with 127.0.1.1.  I have another controller set up the
same way without this issue.  Am I missing something obvious?
