My SLES 10.1 zLinux servers have been notorious for not making much use of the swap space, even when we lower the main (virtualized) in the USER DIRECTORY. We may have something just not configured optimally somewhere, but our luck has gone with adding main Linux memory and subsequently having to add ZVM memory.
