[Bug 2020177] [NEW] Leaking sessions in pam_systemd

[non7top]

Public bug reported:

May 19 12:38:38 s20.wr0.ru sshd[3793128]: pam_systemd(sshd:session):
Failed to create session: Maximum number of sessions (8192) reached,
refusing further sessions.

# loginctl list-sessions|wc -l
8195


 # loginctl session-status 302548700
302548700 - topaz (450)
           Since: Tue 2022-10-18 09:29:02; 7 months 0 days ago
          Leader: 2637625
          Remote: 92.42.15.122
         Service: sshd; type tty; class user
           State: closing
            Unit: session-302548700.scope

# ps axf|wc -l
72


The only way I could figure to fix this is to reboot.
