There's no limit within SYMPHONY itself. Windows, however, limits
processes to at most 2G of memory:
http://msdn.microsoft.com/en-us/library/aa366778%28VS.85%29.aspx
I assume you must be running the 64-bit Windows? What version? In any
case, having 12G does not actually buy you an increase in the memory
accessible by a single process.
Cheers,
Ted
