systemd becomes unresponsive
Issue
When trying to updating glibc package in the context of any service unit in rescue mode, systemd becomes unresponsive, while outputting the following message repeatedly:
systemd[1]: Looping too fast. Throttling execution a little.
Once systemd 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
- systemd
