ATM SVC prefering a subinterface over a phisical

I have had this happen a couple of times and am wondering if it there is someth
ing I am missing. When I set up an ATM SVC on a main interface it works fine an
d pings work but I notice, over time, distance vector routing protocols stop go
ing accross the link. When I defince the circuit as a subinterface it works fin
e. Here are the configs. Is there something which would cause the SCV to close,
 over time?
