Thanks - that fixed it. Changed the code to: 

        if(!open($handles[$i], '|-'))
        {
                # child process
                foreach $handle (@handles)
                {
                        defined($handle) && close($handle);
                }
                child();
                exit 0;
        }

I wouldn't have thought of that, so many thanks - very much appreciated.
