------------------------------------------------
May be I can apply the patch and test with current trunk and see if the negtive
size still persists.
For defaultMemstore also with the PE tool config that we specified you may not
be able to run with 32G and you may need 50G atleast I think. Anyway that is
fine. We need not spend time there now I believe. LEts focus on getting this
in.
I can do the testing and report back by EOD tomorrow my time. Today quite busy
with some other things.
