I'd check your inetd config. Are you allowing sufficient connections and
rate limits for your environment?

Yes, you could always modify your submit_check_result script to take
that into account. Nagios doesn't have that capability itself. The
proper fix however is to determine why the timeouts are occurring. I'm
able to process 3648 passive checks via NSCA every 5 minutes running
NSCA as a standalone daemon. That's why I believe you may need to look
at your (x)inetd.conf.
