CentOS release 6.3 (Final)

I believe this must be something obvious that I have missed. I have refreshed my dev. environment and the default local host checks indicate the following:
[STDERR][EC 126]/bin/sh: /usr/local/nagios/libexec/check_ping: cannot execute binary file

However, I can execute the check without a problem manually from the command line?
Thanks in advance,

Can you try running it as the Nagios user?

Command line as nagios user works fine. I only have the problem from the check in the web interface.

Can you send the output of the following command thanks

[root@nagiosdeva ~]# ls -l /usr/local/nagios/libexec/check_ping
-rwxr-xr-x. 1 root root 99658 Jun 6 16:15 /usr/local/nagios/libexec/check_ping

Can you send the command from your /usr/local/nagios/etc/commands.cfg that you are trying to run from nagios that is producing this error

check_xi_host_ping
$USER1$/check_icmp -H $HOSTADDRESS$ -w $ARG1$,$ARG2$ -c $ARG3$,$ARG4$ -p 5

check_xi_host_http
$USER1$/check_http -H $HOSTADDRESS$ $ARG1$

check_icmp
$USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$

Just to rule out any permissions issues, lets try adding the following permissions to the file and see the issue resolves itself:

No change...For the record, I believe I mentioned previously, that all commands work from the command line. The problem seems to be from the web interface?

Agreed, but the Nagios Core daemon is what executes the check from the command-line as the nagios user, and the output is simply displayed in the browser.

What do you get from running:
