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.
