Since yesterday afternoonn, 1800, this machine runs under a permanent load of 20. We run about 25 smaller numerical simulation, torturing both CPUs. To lock all of the remaining memory, I use memtest from the ports and run 4 of them, each one locks about 300 MB RAM so this machine is now permanently swapping, and hopefully torturing the PCI bus system, the RAID controller and other subsystem. Therefor, this morning, when my colleagues started to work, they set up a high network traffic. I'll keep running this test this day and the following night if no one has a better idea to squeeze out the last performance of this machine to see whether it has a hardware problem or FreeBSD suffers from problems with SMP. :>> In the early time of FBSD 4.3 I have had this problem, too.
