When I type 'ps -weo 'stat uid ppid comm args'' I really see only 10
procs:
 
$ ps -weo 'stat uid ppid comm args'

I've just looked into the portage/package system of this 2 FreeBSD
systems and there is a port for "nagios-plugins" v1.3.1
(net-mgmt/nagios-plugins). This version of check_procs works fine on
FreeBSD 5.2.1 and 5.3! I will make some diff between this version and
your public version if you are interested in fixing this issue. I'll
have to leave now but here some little information for now:

$ ./work/nagios-plugins-1.3.1/plugins/check_procs -v -v -v
/bin/ps -axwo 'stat uid ppid ucomm command'
OK - 95 processes running
