reason for RP Switchover

I am investigating why a RP switched over to a redundat RP.

The router software version is:10000 Software (C10K2-P11-M), Version 12.2(31)SB3c. From the show tech it seems that a bus error caused the problem. I have include a stack trace from the system failure.

Re: reason for RP Switchover

Both RPs are running Cisco IOS Software, and the primary RP crashes due to a software failure, or a catastrophic hardware failure. The table below contains detailed information on the type of software or catastrophic hardware failures that can cause an RP switchover.
