[Bug 948623] [NEW] Can't start more than 35 containers on my machine

[Stéphane Graber]

Public bug reported:

Doing some load testing on LXC, I noticed that I'm unable to start more
than 35 containers on my machine.

The limitation is apparently inotify and the utmp inotify watch:
      lxc-start 1331084250.970 NOTICE   lxc_conf - 'test40' is setup.
      lxc-start 1331084250.970 NOTICE   lxc_start - exec'ing '/sbin/init'
      lxc-start 1331084250.970 NOTICE   lxc_start - '/sbin/init' started with pid '20939'
      lxc-start 1331084251.275 ERROR    lxc_utmp - Too many open files - failed to inotify_init
      lxc-start 1331084251.275 ERROR    lxc_start - failed to add utmp handler to mainloop
      lxc-start 1331084251.275 ERROR    lxc_start - mainloop exited with an error
      lxc-start 1331084251.276 DEBUG    lxc_cgroup - get_init_cgroup: found init cgroup for subsys (null) at /


      lxc-start 1331084251.276 DEBUG    lxc_cgroup - destroying /sys/fs/cgroup/cpuset//lxc/test40

      lxc-start 1331084251.276 ERROR    lxc_cgroup - Device or resource
busy - failed to remove cgroup '/sys/fs/cgroup/cpuset//lxc/test40'


Which seems odd as we're not supposed to use that in 12.04 now that we have the kernel patch right?
