[SOLVED] PAM_SystemD Maximum Number of Sessions (8192) Reached

Iranbingo · 01-17-2022, 09:59 AM

Hi,

After we have updated SLES 15 SP1, Journal shows an Error:

Cron [45024]: PAM_SystemD (Crond: Session): Failed to Create Session: Maximum Number of Sessions (8192) Reached, Refusing Further Sessions.

SSHD [50481]: PAM_SystemD (SSHD: Session): Failed to Create Session: Maximum Number of Sessions (8192) Reached, Refusing Further Sessions.

With the PAM configuration, we have not changed anything.
At Limits.conf, SessionMax was and is commented.
Before the update there was no limit 8192.
Do someone have a idea what happened?

thanks

Apparently Iranbingo already solved their problem here: https://forums.rancher.com/t/pam-sys...-reached/36739
A hit-and-runner...
I'm not so sure about their solution though; but a web search for the error message should shed some light.

Hi,

Unfortunately, this "Thread Tools" -> "Mark this thread as solved" possibility does not exist.

But I have already solved the problem with Systemd as you mentioned.
