To: linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Message-ID: <985967.28848.qm@web45110.mail.sp1.yahoo.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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.
