Script suddenly stops

[Chris]

Dear All,

I'm trying to read ten 200 MB textfiles into a MySQL MyISAM database
(Linux, ext4). The script output is suddenly stopping, while the Python
process is still running (or should I say sleeping?). It's not in top,
but in ps visible.

Why is it stopping? Is there a way to make it continue, without calling
"kill -9", deleting the processed lines and starting it again?

Thank you in advance.
