Hi Sebastian,

Thanks for the details.

I quickly tried with ulimit -n 200 without any problem but I'll recheck
everything when I have more time.

What I don't understand is that when the playlist is shown, lsof on
Cynthiune doesn't list any media file opened, which should mean that the
file handles are correctly closed ?
