The server (vm) used as a management gateway to other service.  Sessions
opened by SSH. Remote machine opens a SSH connection with a key, by SSH
force command, a python script opens, do the stuffs, and exits.

Sessions are in 'closing' state, but no processes (not even zombies) are
exist under this user.

Title:
  logind session files fill up /run space

Status in systemd package in Ubuntu:
  New

Bug description:
  Under Ubuntu 14.10 (server), systemd fills up /run/systemd/sessions directory with files.
  The files are 240-260 bytes, but there are many
   As per default install, /run is on tmpfs with 50 MB size. After a couple of days, /run/ runs out of free space, which can cause not so funny errors, like failed kernel update (kernel postinst tries to create files here, then fails)

  As I see, thesefiles are releated to ssh sesssions, and yes there are
  plenty SSH connection to this host. Shouldn't systemd remove these old
  session files?
