These thresholds were never meant to be any upper limit, the maximum
number
of concurrent checks your box can handle solely depends on your hardware.
See it more like an "if you have a nagios installation which produces
that many concurrent checks - then you should know by now how to
change this behaviour" ;-)
But then - I fail to see how your setup with 322 host and only 35(?)
service
checks could produce that many processes. Maybe it'll be a good idea to
doublecheck what's going on there.
