Prstat indicate size is 3.718GB.. still les sthen 4gb limit

Is that correct?

Subject: Re: RE: OOM error
pmap -rs will tell you what's taking up address space. It could be, for
example,
that you have lots of threads (so the space is gone to thread stacks, so
you might
try -Xss<...> or it could be that you have loaded lots of native
libraries that have
taken up address space, or it could be that you have lots of file
descriptors or
sockets or mmapped files or other native resources that are tying up
your
address space).
(the reference to "swap space" in the message is usuallysomewhat
misleading;
i think there are plans to fix that message to be smarter / less
misleading).
