[nsp] C6500 crash on BGP MD5 session

[Sam Stickland]

Hi,

I recently added our sixth MD5 five to a C6500, and the router rebooted 23
seconds later. Extract from the log files is:

May 19 09:28:48 cat6500-1 23334: May 19 09:28:46.552: %BGP-5-ADJCHANGE:

Router had been running fine before this incident. This is 12.1(20)E on a
Sup2/MFSC2 (512MB on each).

Is anyone aware of any bugs that might had caused this?
