I have a server with 2 Pentium 4 HT processors and 32 GB of RAM, this server runs lots of applications that consume lots of memory to. When I stop this applications, the kernel doesn't free memory (the memory still in use) and the server cache lots of memory (~27GB). When I start this applications, the kernel sends "Out of Memory" messages and kill some random applications.
...you might even need to turn memory over-commit off:
echo "0" > /proc/sys/vm/overcommit_memory
}
That's in 2.4. In 2.6 it's:
echo "2" > /proc/sys/vm/overcommit_memory
But the kernel doesn't honor no-overcommit in either version, i.e. it still
overcommits/pages-out loaded/running procs, thus invoking OOM!
Is there a way to make the kernel strictly honor the no-overcommit request?
