[OpenSER-Users] Openser not processing requests at rate being sent to it

Brian,
I just ran your config file, which is minimal feature wise, and had no
issues. I checked out the latest SVN version of OpenSER, which you may
want to do as well.
Short of that, how about raising the debug level and making it available.
DNS lookups, as Andreas mentions here, can absolutely cause the kind of
problem seen here (though I believe it to be more common on Asterisk).
