The label should probably be something like "dk.hswn.xymon" to  
guarantee uniqueness. (That's the convention used by all the existing

I don't know for certain, but I think launchd should be replacing the  
runclient.sh script, not calling on it. For instance, the script is  
designed to start up the Xymon client and then exit, whereas launchd  
expects the thing it started to keep running. You may have to dig into  
the script to figure out what it does on a Mac and then tell launchd  
to do that. (From just a quick scan, it looks like it needs to call  
`hobbitlaunch` with the appropriate options for your system.)

A list of what launchd expects from the program it calls can be found  
in [the man page for `launchd.plist`][1]. I don't know enough about  
hobbitlaunch to tell you if it meets those requirements, but I'm  
pretty sure the shell script does not based on the fact that it exits.

This might have nothing to do with the error Xymon throws, but it  
would at least explain why launchd keeps restarting the script.
