[c-nsp] Sup-720 fabric failures

Yes we do also have some at one site where they sit at 16-18 celsius ;) all day without issues. Occasionally they complain about low warning threshold but they never fail.

I'm confused how the issue can remain despite a complete component swap, apart from the gbics. Is it even feasible they could cause a SP / fabric crash?

Also just to confirm the original temperature issue is resolved be the kit is back at 21 again now. So this 'new' chassis crash is not a temperature issue I don't believe. Just has the same fabric error / crashdump. Makes little sense to me so I was hoping someone might have either seen something similar with 15.1 or GBICs causing crashes...?
