I remember a few years ago on the 12DS3 engine-0
cards, if a port was subrated using DSU bandwidth, and
was either being attacked or otherwise oversubscribed,
the whole card's buffers would get eaten up.  

The best command to diagnose it in slot X was 

exec X show controller frfab queue 

We'd generally notice it because some non-attacked
customer would be suffering.  The solutions we were
given were cludgy, but WRED helped tremendously.
