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.

Both are relatively new platforms.  9K a little more mature than the ME3600, 
although terminating a bunch of customers on an ASR9K is probably not a wise 
idea yet, given the fact that ISSU is still not there :(

Yes that seems to solve it.

We have invested in ME3600-X and ASR90xx for future scalability. In the big 
picture its awesome but on a personal level it has made me understand what it 
felt like being a Windows admin 10 years ago.

I had the same issue.  Seems to be the result of CSCua60395, at least it was in 
our case.

One thing - I'd suggest getting off of 15.2(2)S as soon as possible.  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 :|

Hi,

Im seeing high CPU utilisation on one of our ME3600-X devices. Trying to
understand what is causing it but my googlefu seems weak.

Anyone knows what the 'AC Switch' process is responsible for?

#sh proc cpu sorted
CPU utilization for five seconds: 48%/27%; one minute: 49%; five minutes:
