Did as you said with same result
put the nrpe.cfg to push debuging to the log file and got this

nrpe[22495]: INFO: SSL/TLS initialized. All network traffic will be
encrypted.
nrpe: nrpe startup succeeded
nrpe[22496]: Network server bind failure (98: Address already in use)

not much help
Running it from xinetd

# PORT NUMBER
# Port number we should wait for connections on.
# NOTE: This must be a non-priviledged port (i.e. > 1024).
# NOTE: This option is ignored if NRPE is running under either inetd or
xinetd

# SERVER ADDRESS
# Address that nrpe should bind to in case there are more than one
interface
# and you do not want nrpe to bind on all interfaces.
# NOTE: This option is ignored if NRPE is running under either inetd or
xinetd

#server_address=192.168.1.1



# ALLOWED HOST ADDRESSES
# This is a comma-delimited list of IP address of hosts that are allowed
# to talk to the NRPE daemon.
#
# NOTE: The daemon only does rudimentary checking of the client's IP
#       address.  I would highly recommend adding entries in your
#       /etc/hosts.allow file to allow only the specified host to
connect
#       to the port you are running this daemon on.
#
# NOTE: This option is ignored if NRPE is running under either inetd or
xinetd

allowed_hosts=216.23.216.20,192.168.1.115



# NRPE USER
# This determines the effective user that the NRPE daemon should run as.
# You can either supply a username or a UID.
#
# NOTE: This option is ignored if NRPE is running under either inetd or
xinetd

# NRPE GROUP
# This determines the effective group that the NRPE daemon should run
as.
# You can either supply a group name or a GID.

# NOTE: This option is ignored if NRPE is running under either inetd or
xinetd

# COMMAND ARGUMENT PROCESSING
# This option determines whether or not the NRPE daemon will allow
clients
# to specify arguments to commands that are executed.  This option only
works
# if the daemon was configured with the --enable-command-args configure
script
# option.
#
# *** ENABLING THIS OPTION IS A SECURITY RISK! ***
# Read the SECURITY file for information on some of the security
implications
# of enabling this variable.

# DEBUGGING OPTION
# This option determines whether or not debugging messages are logged to
the

# COMMAND TIMEOUT
# This specifies the maximum number of seconds that the NRPE daemon will
# allow plugins to finish executing before killing them off.

# INCLUDE CONFIG FILE
# This directive allows you to include definitions from an external
config file.

#include=<somefile.cfg>



# INCLUDE CONFIG DIRECTORY
# This directive allows you to include definitions from config files
(with a
# .cfg extension) in one or more directories (with recursion).

#include_dir=<somedirectory>
#include_dir=<someotherdirectory>



# COMMAND DEFINITIONS
# Command definitions that this daemon will run.  Definitions
# are in the following format:
#
# command[<command_name>]=<command_line>
#
# When the daemon receives a request to return the results of
<command_name>
# it will execute the command specified by the <command_line> argument.
#
# Unlike Nagios, the command line cannot contain macros - it must be
# typed exactly as it should be executed.
#
# Note: Any plugins that are used in the command lines must reside
# on the machine that this daemon is running on!  The examples below
# assume that you have plugins installed in a /usr/local/nagios/libexec
# directory.  Also note that you will have to modify the definitions
below
# to match the argument format the plugins expect.  Remember, these are
# examples only!

# The following examples use hardcoded command arguments...

command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c
