MRTG graph of available system memory show system not using everything before starting to aggressively swap
hmmm...this looks a lot like bz #188141. Can you please try the U4 beat kernel and let me know if this fixes it for you. The kernel is 2.6.9-37. http://people.redhat.com/~jbaron/rhel4/ Found additional information from other people experiencing the same issue in CentOS 4: Bug ID: 0001174 Summary: Extremely high load average and 100% CPU utilization URL: http://bugs.centos.org/view.php?id=1174 Yes, i'm aware of this. I'm pretty sure the U4 beta kernel mention =ed in comment #2 will resolve this issue. Also, just to be clear no VM tuning should be needed. The kernel-2.6.9-37.EL perfectly resolves the problem we were experiencing. Many thanks for your prompt assistance! |
