More from the same machine -- it really doesn't like the script, which
simply does:

nice -n 19 transcode -q 0 -o $FIL.img/$FIL.img -y im -F png -x
ffmpeg,null -i $FIL.avi -c \
0:00:00-0:00:00.1,0:00:10-0:00:10.1,0:00:20-0:00:20.1,0:00:30-0:00:30.1,0:00:40-0:00:40.1,0:00:50-0:00:50.1,\
0:01:00-0:01:00.1,0:01:10-0:01:10.1,0:01:20-0:01:20.1,0:01:30-0:01:30.1,0:01:40-0:01:40.1,0:01:50-0:01:50.1

nice -n 19 convert -thumbnail 80x60 $IMG.png $THUMBS/$IMG.jpg

nice -n 19 montage -tile 15 -geometry +1,+1 $FIL.img/$THUMBS/*.jpg $FIL.jpg

I run the same script on another machine without drama.

Any suggestions? Please cc: me.
