rtkit-daemon flooding syslog

Status changed to 'Confirmed' because the bug affects multiple users.

Hello.

I'm having the same problem with 'rtkit' and log files flooding. Yesterday, I've choosed "menu/logout/halt" option instead of "menu/logout/shutdown". And problems started to happen: I could not even reboot or shutdown computer, because every time when I wanted to do this, there was a window to unblock session (I have had to enter my user password and there was not even internet connection - it could not be connected via NetworkManager! etc.) The only one working solution to shutdown computer was: press "RESET" and next "POWER" buttons. I've decided to try shutdown system via shutdown(8) command but it did not work:

[~]$ shutdown now
Failed to power off system via logind: There's already a shutdown or sleep operation in progress

Anyway, there is not LightDM now! I have to login via "unblock" window mentioned above. And when I want to edit e.g. 'rtkit-daemon.service' file via 'mousepad', there is a WARNING message (** (mousepad:2869): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-*: Connection refused). It happens with every file, that I want to edit etc. But this is not important here. Log files contains many entries related to the 'rtkit-daemon'. For example:

✗✗ rtkit-daemon[1383]: Supervising 0 threads of 0 processes of 1 users.
✗✗ rtkit-daemon[1383]: Failed to look up client: No such file or directory
✗✗ rtkit-daemon[1364]: message repeated 10 times: [ Failed to look up client: No such file or directory]

There is about 30. such entries in '/var/log/syslog/' file etc. Anyway, here are informations gathered via systemd's systemctl(1) command:

[~]$ systemctl status rtkit-daemon.service

I apologize for such a long comment, but 'rtkit' issues, started to happen after described situation. I have no idea if it's important, but it started to happen when I choosed - by accident - 'halt' option instead of 'shutdown' during logout.

● Release: 16.04.4 LTS
● rtkit: 0.11-4

Thanks.

Ubuntu MATE 18.03, Beta 2 with all packages up to date.

Getting this error as well.

User interface is jittery/slow.

With latest update 18.4 lts I have this as well: writing 1GB per day in syslog.

How the heck I stop it? 'vendor preset: enabled'?!?! I reverted to apt-get remove rtkit ...

An easy way to solve this problem is to use the LogLevelMax systemd property:

1. As root, run `systemctl edit rtkit-daemon` to create a new droppin for this service.
2. Add this to the new file:

[Service]
LogLevelMax=warning

3. Restart the service: `systemctl restart rtkit-daemon`

Still same problem on Ubuntu Mantic 23.10
