How are you monitoring this for oversub? SNMP graphs for pps/bps are
not useful nor his looking at CLI pps/bps counters. You should monitor
if there are queue drops on egress. If possible also monitor queue
length, but not all platforms offer this information.
My friend Occam says you're probably dropping packets.

You could also subscribe to the stream with monitoring PC which runs
something like this https://github.com/tarko/CCmon
