Smile Intel64 RHEL system max 32 bit process user memory

I want to know what is the maximal 32 bit x86 process on a Intel 64 RHEL4/5 system.
Is it 4GB or 3GB?
Does anyone have an experience of running 32bit JVM close to this limit (hope it is 4GB)

On a 32bit system, the max amount of memory you can allocate a process is 4GB. On a 64bit machine, that limit is something you probably won't ever reach . However, for java, the maximum is around 3500m.

Are talking about the 32 bit version of the Hotspot-JVM under the 64 bit linux OS?

Are there any limitations to the 64 bit Hotspot JVM version?
