Yep, something is deleting it.
Something with permissions to delete it, which shouldn't be many
things. First make sure that it has the correct permissions, then
check what's running as root.
You might be able to find a process that has a file handle open on
/dev/null or even on /dev itself, but I'd consider that a long shot.
