Hello, from a novice at system administration and systemd. A week ago, I installed Google Chrome on a Debian 11 VPS to get access to a headless browser. Soon afterward, ConfigServer (CSF) began sending alerts that 2 processes were exceeding the limit. These 2 processes are:
/lib/systemd/systemd —user (sd-pam) The VPS only has two (reseller) users that these processes are running under. Searching around, I found an article (*1) that seemed to address the situation. In another article (*2), I found the configuration file, incidentally, with every key commented out. In this config file: /etc/systemd/logind.conf, I added 'StopIdleSessionSec=600’, then restarted logind with: # systemctl restart systemd-logind And checked for status with: # journalctl -u systemd-logind wherein, the following lines are at the end: Oct 23 11:35:39 vps.lan-software.com systemd[1]: Stopping User Login Management... Oct 23 11:35:39 vps.lan-software.com systemd[1]: systemd-logind.service: Succeeded. Oct 23 11:35:40 vps.lan-software.com systemd[1]: Stopped User Login Management. Oct 23 11:35:41 vps.lan-software.com systemd[1]: Starting User Login Management... Oct 23 11:35:41 vps.lan-software.com systemd-logind[94302]: /etc/systemd/logind.conf:43: Unknown key name 'StopIdleSessionSec' in section 'Login', ignoring Oct 23 11:35:41 vps.lan-software.com systemd-logind[94302]: System has /dev/tty0 but not /sys/class/tty/tty0/active which is broken, ignoring: No such file or directory Oct 23 11:35:41 vps.lan-software.com systemd[1]: Started User Login Management. Oct 23 11:35:41 vps.lan-software.com systemd-logind[94302]: New seat seat0. Oct 23 11:35:41 vps.lan-software.com systemd-logind[94302]: New session 2266973 of user root. I think the Chrome installation did something that is causing systemd to start a session, but not close it. How can I get these 2 processes to shutdown? Is this an issue with systemd or in the configuration of Chrome?
