I had a hunch Oracle was involved in this problem.  Oracle
allocates plenty of RAM but does not actively touch all the
pages.  This causes the kernel to mark the pages as inactive
and candidates for swapping to disk.

Oracle has plenty of knobs, both within Oracle as well as the
OS, that you can tweak.  Consult the docs.


On systems with huge RAM (> 16GB), kscand/kswapd can hog
CPU.  There are work arounds/patches for this problem.  Check
if your server is having this problem and needs fixing.
