NRPE mystery

Hello,
I am having really NRPE weird issue, never faced this type of problem before, configured NRPE on hundreds Hosts without any problem but this one is killing me
Environment:
OS: Solaris 10 Zone
NRPE Version: 2.12
Nagios-plugins Version: 1.4.13
OpenSSL: 0.9.8i
Nagios Server: Ubuntu 8.04(hardy)
Nagios Version: 3.0.5
Problem:
I compiled , installed and started NRPE successfully on Solaris 10 zone. But somehow Nagios doesn't show the status critical or warning for this host even services are down. Nagios shows status 'OK' all the time though services are critical
For example
On Solaris 10 zone, nrpe.cfg file has
command[check_users]=/usr/local/sys/nrpe/libexec/check_users -w 2 -c 3
command[check_remote]=/usr/local/sys/nrpe/libexec/check_tcp -p 1250
root at asqstage# /usr/local/sys/nrpe/libexec/check_users -w 2 -c 3
USERS CRITICAL - 11 users currently logged in |users=11;2;3;0
root at asqstage# /usr/local/sys/nrpe/libexec/check_tcp -p 1250
Connection refused
On Nagios Server:
root at cuba:~# /usr/local/nagios/libexec/check_nrpe -H asqstage -c check_users
USERS CRITICAL - 10 users currently logged in |users=10;2;3;0
root at cuba:~# /usr/local/nagios/libexec/check_nrpe -H asqstage -c check_remote
Connection refused
So, it means NRPE is passing write information to the check_nrpe on nagios, but somehow Nagios is showing them as OK status
check users OK 11-20-2008 14:20:41 0d 0h 20m 28s 1/3 USERS CRITICAL - 10 users currently logged in
check Remote Trace OK 11-20-2008 14:16:57 0d 0h 19m 12s 1/3 Connection refused
Here is my nagios configuration
define host{
use generic-host ; Name of host template to use
host_name asqstage
alias asqstage
parents sheila
address 163.189.222.51
check_command check-host-alive
max_check_attempts 10
contact_groups CMESMonitoringGroup
notification_interval 1440
notification_period 24x7
notification_options d,u,r
}
define service{
use generic-service ; Name of service template to use
host_name asqstage
service_description check users
check_command check_nrpe!check_users
}
define service{
use generic-service ; Name of service template to use
host_name asqstage
service_description check Remote Trace
check_command check_nrpe!check_remote
}
Please anyone who can help me in this. I am really stuck into it and can't figure out why it is happening.
Thanks,
