It's a Intel SR2500AL with 32GB of RAM. Looking at the memory usage of the system, something is going totally wrong. The crucial numbers from /proc/meminfo are: MemTotal: 33265916 kB MemFree: 416168 kB Inactive: 24630428 kB (24GB? whooaaa) Another system with only 16GB, same amount of users and load, shows a more normal behaviour: MemTotal: 16619808 kB MemFree: 6912676 kB Inactive: 1774364 kB Why does the 32GB-System have this plenty of inactive memory. Is there a way to find out, what the kernel is holding in readiness? OS: SLES 10 SP1 Kernel : 2.6.16.27-0.9-bigsmp Thanks in advance. Andreas Grimm
