Cisco Switch Crashing - Log Included

Any ideas?

I would like to isolate this issue to 1 unit / component if possible. Otherwise, I will be forced to replace the entire stack.

This is a stack of 6 Cisco 3750 switches.

The stack has been locking up / crashing recently. Typically a power cycle is required to restore functionality. I have it scheduled for replacement in a week or two.

This is an example of my logs on this stack:
