I've been having problems with paging as well since upgrading to AIX
5.3 ML1. I don't have Oracle running on the box either (just Legato).
I've been working with IBM and they keep saying it's an application
problem as they are seeing the system run short of memory and paging
before it basically locks up (unable to fork). Interesting that
someone else is having a similar problem.
