Starting yesterday I'm experiencing machine freezes on a 6.2-R system (remote to me). The strange thing: It occurs twice a day, in the morning hours (both freezes are within 1-2 hours) and for the rest of the day everything runs fine. The machine does not respond anymore (no net, no keyboard interaction) but does not panic. The hardware is a Dell PE-750 and is running for the last 4 years w/o any trouble. It's a gateway system (border router, mail hub etc. etc.) and is also running IPSec tunnels and a poptop server for road clients. My first thought is a hardware problem but why does it occur that less and only in the morning? My next thought is a DoS attack (CVE-2007-0244?) but can that lead into a machine freeze? Is anybody else seeing freezes these days? FreeBSD 6.2-RELEASE-p1 #0: Sun Feb 11 22:35:18 CET 2007 i386 Volker
