Sorry to resurrect this thread, but for various reasons I had to run this task again recently, with exactly the same config lines...
...and it proceeded to eat up my disk space and was still running after 9 hours.
Now, granted, I have a lot of files (269 series, 7728 episodes) but I'm sure this did not happen last time I ran this task.
It created 1000s of /tmp/tmp files and nearly crashed my server.
I just want to update my series list with what I have (based on file name) and then set the 'begin' episode.
What am I doing wrong please?
