Hello everybody,
 
 i got a weird problem with one of my servers. 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 (that's the definition of inactive memory afaik)?
 
 OS: SLES 10 SP1
 Kernel : 2.6.16.27-0.9-bigsmp
 
 Thanks in advance.
 
 Andreas Grimm
