Memory Utilization is 81%

Hi All,

We are using EP core on NW 7.31, Oracle 11.2, Linux.....

Even when no user sessions or any task, or any job running on the application server, memory utilization (not the memory consumption) is 81%.

We have recently added 10 GB of physical memory to the already existing of 16 GB when memory utilization use to be 99% always. After adding extra memory utilization came down to 42% and then again after couple of days shoot upto 81%.

Please guide what to check to know the what is consuming memory even when nothing is going on the application server.

Thanks,

Kumar
