<pre>Component: systemd pid 1
OS: centos 7.0
Summary: systemd --system dbus interface not working after systemd received
SIGQUIT (3) from root.
E. g. `kill -SIGQUIT 1` by root leads to logging something like this:
Dec 22 20:31:39 test systemd[1]: Caught <QUIT>, dumped core as pid 3871.
Dec 22 20:31:39 test systemd[1]: Freezing execution.
After that `systemctl` is useless since systemd isn't responding to dbus
interface:
[root@test ~]# systemctl reboot
Failed to get D-Bus connection: Failed to connect to socket
/run/systemd/private: Connection refused
Also, `reboot` doesn't work:
[root@test ~]# reboot
Failed to open /dev/initctl: No such device or address
Failed to talk to init daemon.
Reproduce: run `kill -SIGQUIT 1` under root.
Env:
- Linux test 3.10.0-123.9.3.el7.x86_64 #1 SMP Thu Nov 6 15:06:03 UTC 2014
x86_64 x86_64 x86_64 GNU/Linux
- systemd-208-11.el7_0.5.x86_64
