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?
OS: SLES 10 SP1
Kernel : 2.6.16.27-0.9-bigsmp
Thanks in advance.
Andreas Grimm

Doesn't sound unreasonable that most of that memory is not in active
use, depending on the applications..
