I have a stack of (3) 2960s 48's running 12.2(55(SE2 code and received the following message:

FYI this caused my whole network to freeze, looked like EIGRP was flapping, Routers were running at >90% and the olny way we got this back was to unplug the fiber uplinks to car-indi0087-sw02, we then plugged them back in and the issue seemed to clear? the only error was the one coming out of SW02.
