Do you mind to give a try with the same 1024m value, AFAIK on a 32 bit box you could go up to 4GB but not higher (that's 2^32 possbile memory addresses).
Another possbile customization could be also to (carefully) decrease the default stack size using the -Xss option in the favour of the heap size, the possible side effect of this customiuzation would be then a StackOverflowError! Hope these will help.
