Your switch is crashing due to multibit ECC errors. Upgrade your ROMMON to 12.1(20r)EW2. You might want to also upgrade IOS to 12.2(18)EW4

You can download it from

Thanks for your quickly response.

But I can't find out the guide about how to upgrade rommon code on Catalyst 4500 switch.

Could you show me the way?

Thank you very much.
