I typically use the system monitor on our SLES11 SP2 server (OES11 SP1). The server has 48 GB of memory as our backup software, Arkeia, loves memory. When monitoring resource usage during an Arkeia backup job, I notice that my memory usage remains around 9.4 GB. However, if I look at the process table, my Arkeia job is using well over 16 GB alone.

So the questions are : Why the difference? And is this a bug?

The one thing that comes to mind is the resource monitor is only looking at OS memory usage and is not adding "user process" memory. Any thoughts on this? Chris.
