This is from a crash file.  What is the real issue? Are you looking for the reason for switch crash?

If so please share the complete crashfile as an attachement. I see this is from  bootflash. Yoy may also look for a crashfile under sup-bootflash: OR sup-bootdisk:

Once you share it I will try to let you know the answer.

Thanks,

Madhu
