The multi-processing support by the Coccinelle software triggers some
development challenges.
If data should be shared between started (background) processes,
an external system need to be selected for the desired storage service.
Thus I would like to send these data over network interfaces by the attached
script for the evolving semantic patch language.

I stumble on the following error message.

I would appreciate if the shown data processing approach can work with
version ranges of involved recent software components.
So I am looking for additional solution ideas.
