( this happends randomly, say, after 3 months of correct functionning ) After reboot, looking at the syslog when the freeze occured, the few ( ~5 ) last lines written show a date which has jumped in the future ( roughly, 15 days ahead ), but nothing related to the crash is logged. our salves machines are ntp-synchronized we run under debian/lenny we launch the machines with the kvm command kernel of host : 2.6.26-2-amd64 kernel of host : 2.6.26-2-686 command launched : kvm -name svn -drive file=xxx -net tap -m 256 -net nic,macaddr=xxx -pidfile /var/run/kvm/xx.pid -daemonize -k fr -vnc :63006 -monitor unix:xx_monitor,server,nowait -vnc unix:xx_vnc If you ever have an idea how to solve or to debug the problem ... Thanks Fred
