Hi Arie,<br>
<br>
Glad to hear that you could fix this!<br>
Otherwise, it can happen sometimes that a cgroup is stuck with
unkillable processes.<br>
It can be annoying because you can't remove the cgroup, so if you
want to start a new one with the same name, you might think you have
to reboot.<br>
If that happens, just try to terminate the other processes running
in the cgroup, rename it ("mv /cgroup/mylittlecontainer
/cgroup/broken") and restart it.<br>
This saved me a few reboots already :-)<br>
<br>
Cheers,<br>
<br>

Seriously, the host machine can not start vservers

With these issues it becomes harder and harder for me to

The patch I sent out on Friday should help handle
that more gracefully -<br>
it moves the cgroup out of the way so a new
container can start. You'll<br>
need to clean the old one up by hand if you care
to, though lxc could<br>
easily provide a tool to clean it up (and move and
analyze any tasks left<br>
running in the cgroup, though I suspect in most
cases there are none).<br>
