Python multiprocessing module

edit

History ... I procured 4 seats in 2018 of version 6. Enjoyed the fork capability at the time. I started trying to debug some code which spawned processes using the multiprocessing module. Decided to try your latest and am in the the process of procuring an upgrade. Same issues. Here the code spawing the process ...

    self.m_print("Plot Otc Constellation")
    p = multiprocessing.Process(name="oiqc", 
        target=self.TaskPlotIqConstellation, 
        args=("OtcConstellation", "oiqc", self.s_nAbort, self.m_devIf))
    self.m_processes.append(p)
    p.start()

Debug seem to be trying ... i'm getting these message in the log file.
