[c-nsp] Recent 3750X oddity

[Bryan Holloway]

After running fine for months or years, over the last 12-24 hours, we've 
experienced spontaneous crashes of Cisco 3750Xs in multiple regions, 
which suggests that perhaps there's some new type of traffic or exploit 
that is causing this to occur.

We are running 15.2(4)4, the latest ...

Before I open up a TAC case, is anyone else noticing this behavior?

... or are we just unlucky?
