When attempting to view a PowerPoint Presentation or a Word document in the Office Online, the user receives an error message indicating that the service is temporarily unavailable. Multiple attempts from the same web application return similar results.
I faced the problem of my Shelly devices becoming regularly unavailable in Home Assistant.Looking at the availability history this problem was quite obvious and especially annoyingwhen a Home Assistant automation (e.g. lights on/off) should run and the Shelly devicewould not respond.
If the Audit rule list includes an Audit rule that contains a subj_* or obj_* field, and the SELinux boolean configuration changes, setting the SELinux booleans causes a deadlock. As a consequence, the system stops responding and requires a reboot to recover. To work around this problem, disable all Audit rules containing the subj_* or obj_* field, or temporarily disable such rules before changing SELinux booleans. 2b1af7f3a8
