>Description:
I have about 5000 PNG images I try to convert into an MPG movie.
ImageMagicks convert can do this. I can convert 100 images, 200
images but somewhere between 201 and 300 images it totally
crashes my FreeBSD box with an endless stream of messages:
"vnode_pager_putpages: I/O error ..."
"vnode_pager_putpages: residual I/O ..."
>How-To-Repeat:
Install graphics/ImageMagick.
Create about 300 PNG files (mine are
movie00001.png: PNG image data, 586 x 533, 2-bit colormap, non-interlaced)
Run "convert -verbose movie*.png blaat.mpg"
Somewhere between image 200 and 300 you get a message about
/var being full and lots of the vnode_pager_putpages messages
scrolling over the kernel.
>Fix:
Euhm... I'm willing to try every patch being send to me.
