Bug#1024080: libpam-systemd: Failed to create session: Maximum number of sessions (8192) reached

[Francesco Potortì]

Package: libpam-systemd
Version: 252.1-1
Severity: normal
X-Debbugs-Cc: none, Francesco Potortì <Potorti at isti.cnr.it>

Starting from a few days ago, I am getting these in my auth.log:

sshd[2108738]: pam_systemd(sshd:session): Failed to create session: Maximum number of sessions (8192) reached, refusing further sessions.

I can regularly log into the machine, but every logging produces the above message.
