127 - plugin may be missing

[forkvoid]

"Return code of 127 is out of bounds - plugin may be missing"

I get that in the Monitoring page. Now, under normal circumstances this shouldn't be a problem--but the problem lies in that one of my hosts works perfectly fine, and the other 38 do not. They are all using one template called "Check Alive" that calls check_host_alive. The file is there, permissions are 755, parent directory is 777. Any ideas on how to fix?

Do you put a correct macro $USER1$ in resource ?
Configuration => nagios => resources.cfg

That's what i thought the problem may be, and I checked that and found an incorrect value. I fixed that last week so it now reads: $USER1$=/usr/lib/nagios/plugins

Plugins are called by $USER1$/PLUGINNAME.
