More RAM is unlikely to help.  You don't say which OS you are using, but
assuming it is not ancient, the issue is how much virtual memory is
available to your process.  If you are using a unix-flavour, you might
look at 'top' to see how much virtual memory your process is using.  Is
your process 32-bit?  If so, you can probably use only about 3 GB of
virtual memory, I suspect you are close to that limit.  If so, you need
to reduce your process' memory usage, or use a 64-bit process.
