Could it be that buffers and flow-control over the 14ms third party leg
are causing the rate-limiting leaky bucket to continue to overflow long
after it's full?
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).
