Return code of 4 is out of bounds

[orani]

I get this critical error "Return code of 4 is out of bounds" sometimes at some checks.

Any ideas?

We need a bit more context.

What plugin(s) are being used for these checks that are sometimes failing? I'm assuming check_nrpe on the Nagios Core side of things? If so, what plugins is check_nrpe calling on the remote machine?

What operating system is Nagios Core installed on? What steps did you use to install Nagios Core?

If the plugin you are running is returning an exit code above 3 it is out of bounds.

Here is the section of the plugin development guidelines which is relevant
