10x more traffic? Yeah that will hit you where it hurts for sure. The
first advise I would give is to look at changing you code to use the
Google hosted version of these libraries:

Yes, 10x traffic will do that. :)

This smells like CF is getting hung and IIS continues to send it
requests.
This leads to a dogpile effect on CF where it's still receiving new
requests from IIS but can no longer respond. This is usually due to a
problem with something getting hung up in your CF code, or with SQL. For
example, a SQL call that never comes back from the database, or some
CFHTTP calls that never hear back from their servers, or a CFLOCK tag
that's in a deadlock.
If this is in fact the problem - the best way to troubleshoot this is
install something like FusionReactor on the server and get a stack trace
while the error is occurring. This will quite literally give you the
exact line of ColdFusion code causing the problem. I'd bet a dollar that
it's one of the three things I mentioned above.
