(usr-tc) Accounting STOP packet problem

After looking over several weeks of data it appears that my STOP packet problem is coming from only a few clients, one using and ascend and one using a cisco router. Is there a scenario where a dropped multilink channel would not generate a STOP packet? Is there a configuration that I may have missed that might resolve this?
