Solaris 10 not appearing to release memory in Update 2

 I'm noticing an odd thing with 06/06 with the 118833-17 R&S patch set - I
upgraded a v890 with 64GB RAM from 01/06 to 06/06, 4 memory hungry zones
running oracle. The system commonly jumps to 62 or 63GB RAM usage, but
doesn't seem to show itself letting go of a lot of the RAM (it will go down
to 50 or 52GB), even when oracle's been brought down and all the zones have
been dropped. prstat -a (or -z) is so bad about reporting the RAM in shared
memory
 it's difficult to get a handle on what could be happening.
