[c-nsp] Cisco 3750 Stack crashing

[William]

Hello list,

I'm getting these error messages from one of our 3750 stacks, the
stack consists of two 3750s and last week the slave crashed causing us
to move all the ports onto empty ones on the master.

No major network changes have been introduced, nor have we changed the
config, no new applications or users have been introduced either.

I've enclosed sh ver info and some logs..

The slave switch is getting turned off as its not being of any use at
the moment and may effect the stack.

Any input is welcome, thank you for your tmie.

Regards,

Will
