Failed to allocate 1934MB shared memory

I’ve a server that is running Windows Server 2003 R2 Enterprise Edition SP2 x86.

I just noted that you cannot allocate shared memory beyond 1.6GB.

Is this a known problem between Cache and this OS architecture, and has anyone configured it beyond this?

Cache gives the below errors (Version: Cache for Windows (x86-32) 2012.2.5 (Build 962_1) Wed Jun 11 2014 13:58:32 EDT).
