Or you are losing line protocol keepalives of some sort (e.g. at L2), or
routing protocol packets. It may also be that your MPLS provider limits
the traffic at X kbps INCLUDING protocol overhead - if so it's going to
police out all sorts of important stuff (assuming you are running FR, ATM
or something rather than some sort of TDM over MPLS).
