I did find this report, assuming that your Option 11c is a release 03.00 or later.
I would follow the method to check your "z" drive for disk space first!.
There were special patches issued as release 04.00 and I think 04.50 that stops the other patches from being dumped onto the "z" drive. This is why it is important to know the software version.
