[c-nsp] High CPU ME3600-X

[David Farrell]

Just to add my £0.02 worth.

We've been hit by issues in 15.2(2)S with respect to memory leaks in SSH 
and also wacky forwarding behaviour in bridge-domains where 
double-tagged frames are involved.

Not fun, but looking good thus far on 15.2(4)S2.

David.

I've had numerous issues with this train (including S1) - random lockups of switches (no bug id) requiring power cycle and MPLS issues TAC *thinks* they have identified as CSCtz16622 which is fixed in 15.3(1)S, but they aren't sure :|
