I presume the same problem on my server, but I cannot debug it because
it seems to lock-up hardly, with the console not visible anymore.

After some quick googling I found an ugly patch on the openvz list:
http://openvz.org/pipermail/devel/2008-July/013096.html

It would probably safe the machine from panicing... but not much more...

Judging for the package the problem may as well be grave..

Kind regards,
