I have all new hardware and running 2 IDE local drives, nothing's faulty. Everything is working fine now that I have downgraded to 5.2.1. I have no kernel dump either since it's a problem with software disk write buffer. But, at least, you get a message of what could be the problem, I only got dead freezes. For me, it wasn't heavy loads that was crashing it, but only buffers getting full. At the moment, all I can say to help is, if you use dummynet or altq, be sure to have HZ=1000 in your kernel. But that won't help you much because your server was working fine. Good luck, DrVince DrVince@anonymnet.net
