I am using Redhat 9.0 and I have a memory problem. I have a parent process and child processes which are created on demand by forking at the main process. They use a shared memory to share some data. I monitor the memory usage by Redhat 9.0's own "system monitor" tool. It has three fields in the memory usage field : Total, RSS, Shared. Do you know what these fields exactly show?
My problem is that altough I don't use any dynamic memory allocation, my processes' total memory usage increases (all of the Total, RSS, and Shared) when I write some data to shared memory. The worse is that this total memory usage passes to child processes, which are created for any client requesting connection. I know that shared memory is kept at the kernel and not duplicated for the child processes. am I wrong or another problem exists?
Please help me!
Thanks for your help in advance.
