[Lxc-users] LXC: missing /dev/pts/nn

[Gus Power]

Hi,

I've got a box with 15 lxc containers running happily. However I tried
to setup another container today and met with some resistance:

      lxc-start 1307376067.433 WARN     lxc_cgroup - using deprecated

Looking in /dev/pts I see that for some reason 26 is indeed missing:
> ls -alh /dev/pts/

I'm loathed to just try and make another device node and hope for the
best. Can anyone shed some light on what may or may not be happening here?

Thanks!

Gus.
