On a CentOS 7 server I'm getting this error while trying to reboot:
# reboot
Error getting authority: Error initializing authority: GDBus.Error:org.freedesktop.DBus.Error.LimitsExceeded: The maximum number of active connections for UID 0 has been reached (g-dbus-error-quark, 8)
Failed to start reboot.target: Connection timed out
Or to restart Apache httpd:
# systemctl restart httpd.service
Error getting authority: Error initializing authority: GDBus.Error:org.freedesktop.DBus.Error.LimitsExceeded: The maximum number of active connections for UID 0 has been reached (g-dbus-error-quark, 8)
Failed to restart httpd.service: Connection timed out
What do the mentioned active connections refer to? How do I stop some of the active connections that are not needed anymore in order to free some slots?
