Just curious; why are you running MPLS and your core-facing 
features on an SVI?

Also, you're lowering your protocol MTU's quite a fair bit, 
even though the physical interface can handle them. Any 
reason why?

Have you tried running all this on the 10Gbps uplink ports 
natively, and checked again to see whether you see these 
issues?

I can't recall for which platform, but I think there are 
some restrictions with running MPLS and/or MPLS-TE on an 
SVI.

Mark.
