I am having the same issue on Ubuntu 16.04 now. All sessions appear to
be for one user that is used for incoming ssh connections for rsync.
Here's an example:

$ loginctl show-session 59
Id=59
User=1004
Name=raccess
Timestamp=Чт 2018-03-29 20:20:03 MSK
TimestampMonotonic=1763641802
VTNr=0
Remote=yes
RemoteHost=216.126.59.227
Service=sshd
Scope=session-59.scope
Leader=2814
Audit=59
Type=tty
Class=user
Active=yes
State=closing
IdleHint=no
IdleSinceHint=0
IdleSinceHintMonotonic=0

I don't see any processes running under user raccess apart from system
ones:

$ ps aux | grep raccess | grep -v grep
raccess   2822  0.0  1.6   6384  4132 ?        Ss   20:20   0:00 /lib/systemd/systemd --user
raccess   2823  0.0  0.4   7316  1096 ?        S    20:20   0:00 (sd-pam)

And here's an output of lsof -u raccess: https://pbin.cf/444b2d29

This is happening on two servers.

Title:
  logind session files fill up /run space

Status in systemd-shim package in Ubuntu:
  Confirmed

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?
