A process in uninterruptable state cannot be killed. Killing the parent
will not help. Rebooting is the only way.
Processes gets stuck uninterruptable primarily due to kernel races
or bad drivers. I would suggest that you update your kernel and
test your hardware.
Without looking at your application and the script that's causing
the problem, the only thing that can be said is "contact your
DB and OS vendor".
Further, if a process is stuck in uninterruptable sleep, it increases the
system load by 1.0. If several processes are sleeping, load average
will shoot up inspite of the fact that all the processes are just sleeping
and the machine is fully responsive. Daemons like at, sendmail, etc
will stop normal operation during high load and create further headaches.
