What might this mean? On UNIX computers, each process gets a couple of  
address spaces on their own, like function stack, heap, program static  
data; on a 32-bit machine they are typically 2 GB each and handled by  
virtual memory, built into the OS. One can check usage by commands  
like 'systat vmstat', 'vm_stat'. If there is too much paging, there is  
too little available RAM relative the programs in use.
