Re: [Wrapper-user] Wrapper memory settings issues?

[Gil A. <gi...@gi...>]

As I understand it, and I could be wrong...  32-bit windows has limits on 
the maximum contiguous memory a process can allocate to itself (About 
2GB).  Plus, there is some overheard with the JVM and associated 
objects.  Depending on the machine you have and your JVM, you probably will 
not be able to allocate more than 1.5 GB.  The most I've ever been able to 
allocate on a 32-bit Windows box with a 1.4 JRE is 1450M.

For more info on this see:
