https://bugzilla.novell.com/show_bug.cgi?id=392585 Summary: Dom0 instability and log messages under heavy load Product: openSUSE 11.0 Version: Factory Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Xen AssignedTo: cgriffin@novell.com ReportedBy: frank.arnold@amd.com QAContact: qa@suse.de Found By: --- We installed openSUSE Beta (currently 3) Xen on two systems and ran some tests on it. Dom0 becomes unstable if we start enough guests which are running different stress tests. This can be seen by VNC connections of the guests not getting updated properly. Eventually, it recovers after some time. But we saw a complete lockup after 2 days of runtime with some overload, too. Another indication is that we are getting lots of the following logs inside /var/log/messages, even with moderate load: klogd: clocksource/{0,1,2,3}: Time went backwards: ret=12f357ae516ad delta=-17749258 shadow=12f356f3bdd4e offset=cb83438 We are not seeing this with upstream Xen.
