(Return code of 126 is out of bounds - plugin may not be exe

[toleolu]

I copied a plugin from our old nagios server to our new Nagios XI, but I get the above error.

I've confirmed the file is executable, nagios is owner, all that is good, but if I run the plug from the command line, I get this:

-bash: /usr/local/nagios/libexec/check_vtc_rad: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

Can someone shed some light on what that error means??

Thanks

Think I might have found it, the old Nagios is a 32 bit machine and the new Nagios XI is 64 bit.

Anyone have any suggestions on how I can run my old 32 bit plugins on the new 64 bit system?

I found it, yum -y install glibc.i686

Maybe posting this will help someone else someday.
