Problem: elogind (sysvinit hosts) creates one cgroup per login session at /sys/fs/cgroup/<session-id> and never removes it. On one server a CheckMK's per-minute SSH logins leaked 65533 of them, which exhausted the kernel's memory cgroup IDs and made every docker build/docker run fail with device or resource busy.

Workaround: hourly cron job that does cleanup

Is this a known problem? Is there a better solution?
