Always try kill -9 pid if plain kill (which is kill -15, or "TERM") doesn't
work. kill -9 ("KILL") can't be ignored or caught, but it doesn't give the
process a chance to clean up after itself.

The "D" state means the process is in uninterruptible sleep.
Uninterruptible processes can't be interrupted by signals, which is why you
can't kill it; they can only be woken by the kernel. Normally this only
happens when the process is blocked in a device driver waiting on hardware.
