Hi John,
I was hoping it would, yes. Does websphere not release memory back to
the OS when it not longer needs it? I'm concerned that if the memory
spiked for some reason (indexing a large document) then that would
hamper the rest of the OS because it'd hold on to far more memory than
is needed.
Thanks,
Rol.

garbage collection and there is significant dark matter in the
allocated memory.
Are you expecting the process to shrink? They don't normally.
