Hi, hmm, isn't vwait --timeout 30 supposed to time out after 30 seconds and go wild on your remaining processes? (this one is for enrico) There was a classical bug in the signal handling (glibc does not interrupt vc_wait_exit() but restarts it by default). I tested the dietlibc version only which does not show this behavior. There was a race also which could cause non-timeouting when the system time was modified in the wait phase. Both issues should be solved in CVS. On WBEL4 there's an issue with minilogd, which seems to keep the vserver-stop hanging and then complaining... I renamed the minilogd file, so at least that one won't cause any problems... /Brian ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

Re: [Vserver] vserver-build problem ?
By the way, is this warning problematic ? *You are using a version of yum which is insecure and broken in chroot related operations; either apply the patches shipped in the 'contrib/' directory of util-vserver, or ask the author of yum to apply them (preferred). In the meantime, 'vyum' will continue with dirty hacks which might not work when the vserver is running and local DOS attacks are possible. * regards, Jean-Christophe Petit wrote: I found the problem Oups, my /dev/ is now almost empty ?

What was the reason ? we switched to network context, with similar properties like the process contexts (which are also not allowed to migrate into eachother) maybe in the future, when the 'admin' context becomes a flag, we will allow to migrate between contexts (but there is really no demand for that atm) HTH, Herbert - Jacques Gelinas [EMAIL PROTECTED] dav_ufs: Access your home directory using WebDav http://www.solucorp.qc.ca/miscprj/dav_ufs.hc ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
