Hello everyone,
I'm frequently seeing errors in the logs upon VE start and during a
heavy I/O (cp /something /somwhere on HN) I had a lockup and kernel
panic but did not have a serial console attached to catch the panic
message sorry.
Is this a bug? I found http://bugzilla.openvz.org/show_bug.cgi?id=470
with similar problem but it says the bug is fixed(?)
the errors look like this:

using debian etch with packages from systs.org - are the CentOS kernels more stable?
