we have had an issue with a 6506 box (with SUP2) - it was reloading every 15 minutes or so, until we shut down an interface with a lot of BGP peers on it (I mean a lot). After that the switch has become stable. We have been trying to identify what may have caused the condition.
Sh ver shows this:
System returned to ROM by power-on (SP by error - a Software forced crash, PC 0x4012533C)
I have run sh tech through the output interpriter and it did not come back with anything specific really.
Could it be CPU overload?
