No output returned from plugin

[Alexander Haas]

Hi list,

it's me again :)

I wrote a plug-in which does work great. It works from the shell as 
root, from the shell as nagios and from nagios executed as plug-in.

The only problem is when there is an error returned. It does not work 
when i execute it from nagios as a plug-in and there is an error (=> 
return code != 0). Every time my plug-in returns anything but zero, 
Nagios tells me that there is "No output returned from plugin". It does 
not matter if my script does output its error message on STDOUT or 
STDERR. Of cause there is an error message visible when I execute my 
plug-in from a shell.

I guess there is an easy explanation?

Thank you very much,

Alex
