Nagios looping, causing hundreds of procs!

Ok, no change so far, I'm going to now try turning off the
command_check_interval on the central? nagios box.  /me crosses fingers.

I'm doing ~40 checks per distributed host.  They are fine, and the central
server seems to handle the checks quickly enough (up until there are
hundreds of nagios procs running!).  I will attempt one thing at a
time...first I've pushed the status_update_interval to 120 from 15
(default?).  I should know shortly, at least by the end of the day if its
helped.  If not at that point I'll try the check_command_interval.  The
other suggestion, fixing the host-check-command...I'm using standard
modules, like check_tcp etc, and I cannot pinpoint one particular service
check that's actually causing another nagios to spawn.  WE'll see

Thanks,
Dave

How many checks are you doing? Are they coming in faster than nagios can
process them? How about your host-check-command? Remember that your
central server will try to execute the host-check-command for any
services that come in as critical. If it can't reach the device hosting
the service you may need to change your host-check-command for that
device on the central server. Additionally, try setting
command_check_interval=-1 in nagios.cfg. You might also want to increase
your status_update_interval (I've got mine set to 120 seconds).
