How many passive service check results per second ?

Hi,

we have set up Nagios with ditributed monitoring.
The Nagios-Master gets only passive service check results
fron the distributed monitors (about 8000 per hour)
and does not run any eventhandler.

We see a lot of failed send-nsca commands on the disributed monitors
and the external command file at the master is most of the time
nearly 4k big (is this the maximum for a FIFO-stack ?)

Setting the command check interval to 2s results in an increasing
number of nagios processes, but the external command file becomes
only 1.5k big and most send-nsca are successful.

What is the maximum number of passive service check results nagios
can handle ? It is running on a dual PII 1,26Ghz with 1GB RAM.

Thanks
Bernhard
