Hi Rob,

like i mentioned when I posted this question any output of the script itself is discharged by the TEST::HARNESS module!.
So also the warnings!
Thats is why I output to a log and write some informations to check if the script runs.
It looks that is runs o.k, but I have no idea if it exits or not. When it does not exit the pove or TEST::HARNESS can not proceed and will hang.
I need to understand who the control gets back to the module that calls my script when I do either a prove or a make test.
