Need high frequency ping checks

[Todd Blum]

Hello,

	At my organization, our monitoring requirements for our client's WAN
interfaces is to ping them once per second.  I am using Nagios 2.10
(bundled with Groundwork VM 5.2.1).

	I have set interval_length to 1 in nagios.cfg.  Nagios starts to ping
once per second, but then stops for 20-25 seconds at a time before
resuming.  Is there any way to have Nagios ping evenly once per second?
I am attaching the nagios.cfg and copying the relevant portions of it
below.

Thanks for your help,

Todd
