Package: kernel-patch-openvz Severity: normal Tags: upstream Version: 028test002-3
Hi again Some more testing show that the patched kernel is not perfect. I get an error message when stopping my virtual server. Do not know if this is a real problem yet though. Do not know if it is in vzctl or the patch either right now. Suspect the kernel though. Here is the log from syslog about this new issue. I have started and stopped virtual server 1 a couple of times. It happens on every stop.
