But for me it crashes within a couple of days. The system is a HP Proliant DL380 G3. Which mean it runs ciss(4) and bge(4). Its a generic SMP kernel, but I have tried without SMP enabled before. The system is running the news software Diablo and are set up as a feeder. Give or take aprox 100 incoming connections feeding aprox 200Mbp and 20 outgoing feeding aprox 200Mbps. I have tried to follow the docs about creating a dump into /var/crash. But there is none to be seen. Perhaps I have missed something, or it is actually not created. I will go through those again once I am back at work on tuesday. It feels like its just freezes and reboots without any warnings at all. If someone will give me a simple step by step walkthrough, I can make it in whatever way you want me to. /Bjorn
