If you only have 562 MB of virtual memory available, and you try to run
a Java process with a 512MB heap, it's not going to work. On the system
I have running now, with a DAS heap size of 512MB, the virtual memory
size of the DAS process is 831 MB. This extra space is for the code and
stack areas of the process.
