I apologize if i was not clear enough. What i wanted to convey was that the same process under same amount of load is showing big difference in the amount of virtual memory consumed in different servers, one the client server and second our internal server. So, I wanted to know if the virtual memory value is dependent on some system parameters and how to check those parameters in both the machines.
