Comment 8 for bug 1426362

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.
