Looks like something has tried to do something like "> /dev/null"
without the device actually existing - looking at the file contents will
probably give a hint as to how it happened...

To correct it, remove /dev/null, and re-create it with:

mknod -m 666 /dev/null c 1 3

I.e a character device, major/minor pair of 1,3, and world-writable.
