First thing I would check is traffic-shaping parameters.  Ask your ISP for
_exact_ shaping specs for your PVC.  If there is a mismatch on either side,
one of you will drop cells.

Once a single cell drops, you start re-transmitting entire packets... Then
you might drop a cell from the re-transmitted packet..... basically all hell
breaks loose.

Hope this helps,
Travis
