[c-nsp] Run-away IP SLA process on Catalyst 4948

[Rick Ernst]

I'm working on seting up an IP SLA responder on a Catalyst 4948.  Something
has become confused, and CPU is getting hammered.  There are no current
probes being directed at the device.

During initial testing, I played with various configs getting control
channel and authentication setup.  I've ended up with two identical lines in
the running config that can't be removed, and CPU is >90%.

ip sla responder udp-echo port 5558
ip sla responder udp-echo port 5558
ip sla key-chain SLAK

#no ip sla responder udp-echo port 5558
%Responder not found

Any suggestions for clobbering the responder? I'd rather not reboot if
possible.

Thanks,
