Can you post parent interface and sub-interface output as below :

show interface g0/x and g0/x.1

what kind of traffic on that interface ? (what is the use of that interface transit ?)

You could also use the command "show asp drop" to see what is being dropped. If you want you can also issue the clear asp drop command first to clear the counters. Then see which counter is being incremented faster than expected.
