Well, there is a memory leak in WAS 6.1.0.7 and 6.1.0.9 which is why
we're trying 11 (PK46366).  I'm hoping the app doesn't have any.
Just got there so we will be watching it.

I wonder if kernel setting vm.swappiness needs to be much lower than the
default of 60 in this env.  I recall Nationwide saying something about
that at SHARE...

Hmmmm I wonder if this could be a symptom of a JVM memory management
issue: memory leak, poor garbage collection? Is the problem getting
worse as time goes on?
