Re: [Xen-users] memory problem

["John Fairbairn" <webmaster@xxxxxxxxxxxx>]

Hello,
   I just had this exact problem, had about 8, Domain-24 - Domain-32 all
unkillable. Had to shut down all running domU's, xend restart, and then
there were still some left, so without any domU's running do
xm destroy <domain>
til they are all gone, I was able to clear it all up w/o rebooting the dom0
and restore full functionality.
   If anybody has Idea's on why this might happen I'd love to know as well.

Regards,
John Fairbairn

In the game of life it takes a root prompt to really foul up.
