Kernel eating memory, ends up trashing

[Dag Wieers]

Hi,

On August 8 I added a bugreport for a machine that trashes aprox. every 2 
weeks because of the kernel eating memory. You can find it here:

	http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=97546


I've also made some graphs available together with some command output 
that clearly show it is a kernel problem:

The behaviour of the system has been like this since I installed RH9 
(kernel 2.4.20-8) and newer kernels (2.4.20-18.9, 2.4.20-19.9 and 
2.4.20-20.9) and continues to act like this ;(


I know at least 2 other persons that have the same problems (on different 
machines with a similar workload/functionality) so it seems to be a bug in 
the kernel on a particular use of the VM.


Anyone else noticed something like this ?
