Segmentation fault while running several instance at the same time

[gael]

I run this command :

ffmpeg -i /var/www/dp/d2d/index.html?d=36UM193O -ss 00:00:18 -r 1 -vframes 1 -s 800x600 -f image2 -y /var/www/dp/pics/36UM193O-18.tiff

for distinct video files at the same time, i've this kind of output:

ffmpeg -i /var/www/dp/d2d/index.html?d=36UM193O -ss 00:00:18 -r 1 -vframes 1 -s 800x600 -f image2 -y /var/www/dp/pics/36UM193O-18.tiff
