Alexander,

http://freevps.com it's the first time i see ist. .. It look like a
completly other software to run vserver... many work to change kernel and
tools on a runnung vserver. and the server is public and productiv.

all other vserver running .. only one IP Address have this problem. and
befor, the IP was running too. I think freevps can fix my problem, but it
is not a solution to remove my vserver software and kernel.

tonight I try a reboot and will see it is a wrong cached route.

reboot is not a solution but a workaround :-)

cheers, Brian

Brian, to avoid this problem the vserver strongly requires to mark all
kernel
route cache entries with context id or to separate this route cache table by
contexts.

this has already done several months ago in freevps project
(http://freevps.com), but not implemented into the vserver project yet.
