 Hi, I have a RHEL 4 server. It has 12GB RAM, when I issue a free command it shows 11GB as used. But I don't think so the proceses are using such a huge amount of memory since the sum of memory used by all the processes in ps -aux command is not equal to the total used memory shown by free comand.The used memory size on that server keeps on increasing. any reason why?After it reaches more than 11GB the size of used memory suddenly drops and becomes 2 GB.

What is the actuall memory that my server is using at a particular point of time?Please suggest. Thanks,Ajay
