Yes, find the program that is eating up memory. Get the vendor to fix it.
If it's not a program, it's the OS, so get IBM to fix it.

#1 - The paging space is not a filesystem.
#2 - It means that hd6 is fragmented at the LVM level (i.e. LP's scattered
instead of contiguous).
- Never have more than one paging space per disk.
- A paging space should be made of contiguous PP's.
- If you have a VG with two paging spaces (one on each disk) and
decide to mirror the vg, don't forget to remove one of the paging spaces.
Doing AIX support was the most monty-pythonesque
activity available at the time.
