[vserver] networking probleme: chbind

Hi all,
        I've upgraded from 2.8.18 to 2.6.22, and
#chbind vserver foo start give:
ncontext: vc_net_create(): Invalid argument

I've seen in the doculentation that i have to specify the listen adress,
but I was wondering if it was possible to have same services on the same
ports, without changing local service configuration file.

files:
ncapabilities:
^12

bcapabilities:
NET_BIND_SERVICE

context:
3

util-vserver 0.30.214-5
thanks for your help
