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. -- You received this bug notification because you are a member of DX Packages, which is subscribed to systemd-shim in Ubuntu. https://bugs.launchpad.net/bugs/1426362 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.
