nrpe (No output returned from plugin) works fine from cli

[Corey Van Allen]

I'm having an issue with nrpe where I can run 
/usr/lib/nagios/plugins/check_nrpe -H 206.135.x.x -c check_load
and it returns
OK - load average: 0.88, 0.65, 0.59
but the web client shows (No output returned from plugin). I have
debugging on client side and will see the cli connection from the
server, but nothing from the daemon. I have tried debugging the plugin
using this information, but the file is never created.
http://www.nagios.org/faqs/viewfaq.php?faq_id=162
Looking through the archives, I've seen that -a $ARG2$ should be
removed if not using arguments, which I'm not, so I did. No change.
Here are the relevant file contents
/etc/nagios-plugins/config/check_nrpe.cfg 
define command {
        command_name    check_nrpe
        command_line    /usr/lib/nagios/plugins/check_nrpe -H
$HOSTADDRESS$ -c $ARG1$
}

services.cfg
define service{
        use                             generic-service         ; Name
of service template to use

        host_name                       linux
        service_description             LOAD
        is_volatile                     0
        check_period                    24x7
        max_check_attempts              3
        normal_check_interval           5
        retry_check_interval            1
        contact_groups                  foo-admins
        notification_interval           120
        notification_period             24x7
        notification_options            w,u,c,r
        check_command                   check_nrpe!check_load
        }
 
client side
/usr/local/nagios/etc/nrpe.cfg
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
BTW, This happens with all the nrpe commands not just the load.

Ideas? At this point I'm baffled.
