New version 2.6.31.5/vs2.3.0.36.23 is out. Please bump it to the portage. As a side note: current stable version 2.2.0.7 is not compatible with two stable packages: udev and gcc.
VServer based on 2.6.31 might get stable status, based on the mailing list http://list.linux-vserver.org/archive?mss:3038:200910:bandfaahcicaapnnoenb So please give gentoo users a change to test it too.
Not sure if vserver team seen that bug, but that version is in the portage. Closing ...
