Since today when I try to execute systemctl commands using root account they fail with Timeout error:

>sudo systemctl
>Failed to list units: Connection timed out

Same occurs with systemctl start or systemctl stop commands when ran as root.

If I try to run the same commands using an user account they work (except start and stop due to lack of permissions in user account).

If I reboot the server all services that I'm aware start correctly but I'm I get the same timeout errors.

Can someone give me some clues of how to troubleshoot the problem?

PD: Using openSuse 13.2 (Linux version 3.16.7-21-default)

Since today when I try to execute systemctl using the root account they fail with a Connection timed out error:

The same thing occurs with systemctl start or systemctl stop when ran as root.

If I try to run the same commands using an user account, I don't get the Connection timed out error (start and stop give the expected error due to lack of permissions in user account).

If I reboot the server, all services that I'm aware of start correctly but I still get the same timeout errors.
