One last thing if I may: what do you think is better, restart of the service or reboot of the vps? except for the additional logging, is there something I should be aware of when editing the above? Thanks

In auth.log I see a lot of su[12936]: Successful su for domain by root su[12936]: + ??? root:domain systemd-logind[148]: New session c315 of user domain . su[12936]: pam_unix(su:session): session opened for user domain by (uid=0) su[12936]: pam_unix(su:session): session closed for user domain in syslog, I see a lot of systemd[1]: Started Session c314 of user domain. systemd[1]: Started Session c315 of user domain. domain is the user of my virtual server defined in the VPS. c314/c315 increased by 1 each time, every 5 minutes (see explanation below). When running `loginctl list-sessions` those sessions number grow as "active=yes" and "state=closing" and never disappear from the list. a random session as an example: loginctl session-status c315 c315 - domain (1000) Since: Sat 2020-02-08 20:27:08 UTC; 23h ago Leader: 12936 TTY: ??? Remote: user root Service: su; type tty; class user State: closing Unit: session-c315.scope I did a simple test: logged in with ssh, logged out (exit) and re- logged in. I saw 2 sessions in loginctl list-sessions and the previous one, which I obviously closed, never disappeared from the list. as a "bonus": Virtualmin apparently open/close a session for the virtual server user to do its stuff causing the number of ghost sessions to grow forever... I posted this question in server fault, askubuntu, ubuntuforums and virtualmin - no one knew what to tell me. I have no idea what/where to look for... Please advice :) Thanks in advance. FWIW: Someone from virtualmin forum told me that he had a similar problem with debian 9 and it was fixed in debian 10. After a boot I see this, maybe related?
