Topas is an excellent resource.  Thanks for the pointers.  The attached is the current state, and I can plainly see that I have 6GB available.  It's also showing the server at low utilization after an application hang.  This will really help us diagnose what's wrong.

Knowing that svmon reports on 4k pages is something we'll never forget again.
