<DIV>Alexei,</DIV>
<DIV> </DIV>
<DIV> I am not a Linux kernel specialist, but generally
memory on the "buffer cache" is on a different "list" than memory "free", so
the kernel has to reclaim the buffers from the buffer "list" to release
them to the "free" "list" as memory pressure increases.</DIV>
<DIV> </DIV>
<DIV> This has a processing cost. And on large database servers is
undesirable as the database does not use the buffer cache, so we have the
processing cost without any benefit.</DIV>
<DIV> </DIV>
<DIV> Usually on a database environment I tune
the kernel as to keep a large amount of the memory on the "free" list, so that
it be readly available when spawning new database processes.</DIV>
<DIV> </DIV>

<DIV>Alexei,</DIV>
<DIV> </DIV>
<DIV> Yes, it seems to have no effect, which too is very
strange. On 2.4 vm.freepages had a very easy to notice
effect.</DIV>
<DIV> </DIV>
<DIV> There are other people having problems with buffers
not being released on the list and some of them are forcing the kernel
cache to be flushed with:</DIV>
<DIV> </DIV>
<DIV>echo 3 > /proc/sys/vm/drop_caches</DIV>
<DIV> </DIV>
<DIV> But I dont see this parameter on RHAS
4.0.</DIV>
<DIV> </DIV>
<DIV> Also, to be fair this seems to be a
generic VM issue, I see this on servers that are not running ocfs2
too. And I only see this behavior on machines with more than 2Gb of
memory.</DIV>
