Though you did not tell us, I believe you are using a 32-bit system, 
which mean that depending on the combination of hardware and operating 
system, a user process can get between 2 and about 3 GB of virtual 
memory maximum. This is hardware (Intel, AMD, PowerPC, Sparc, 
...)/operating system (Linux, UNIX, MAC OS X, Windows 
98/Me/XP/Vista/Server2003...) dependent.

ClearSystemCache["Numeric"] or ClearSystemCache[] might help reclaiming 
some memory (assuming you are using version 6.x.x).

http://reference.wolfram.com/mathematica/ref/ClearSystemCache.html

Anyway, it is really hard to be specific without any hint about your 
hardware, software, and the system you are trying to solve.
