Logging in from hundreds of terminals makes system unresponsive
Issue
When logging in to the server from hundreds of individual terminals, dbus-daemon process on the server could become unresponsive while holding CPU 100%.
Once dbus-daemon process becomes unresponsive, any systemctl commands relevant to D-Bus connections fail. For example, the following systemctl commands cannot be executed:
- systemctl start
- systemctl stop
- systemctl restart
- systemctl poweroff
- systemctl reboot
Environment
- Red Hat Enterprise Linux 7
- accountsservice
