Restart on crashes

Warning: If you encounter crashes with AlexaPi, please report them, so we can fix them. That is the solution. This feature exists as a last resort when for example the app crashes after several weeks of operation due to some memory leak and there is no obvious way to solve it.

Systemd

This feature is controlled by a systemd unit override file /etc/systemd/system/AlexaPi.service.d/restart.conf.

If you wish to enable it: sudo cp /opt/AlexaPi/src/scripts/unit-overrides/restart.conf /etc/systemd/system/AlexaPi.service.d/

And to disable it: sudo rm /etc/systemd/system/AlexaPi.service.d/restart.conf

And sudo systemctl daemon-reload for the changes to take effect.

Classic init scripts

The feature is controlled by the presence of /etc/opt/AlexaPi/monitor_enable.

If you wish to enable it: sudo touch /etc/opt/AlexaPi/monitor_enable

And to disable it: sudo rm /etc/opt/AlexaPi/monitor_enable

Temporary setting

To prevent the re-spawn from happening, add a file called monitor_pause into the /run/AlexaPi directory. sudo touch /run/AlexaPi/monitor_pause will do the job. This will prevent the script from creating a new instance of AlexaPi, and a kill command will now truly kill the alexa program. sudo rm /run/AlexaPi/monitor_pause will return to re-spawning.

After a reboot, AlexaPi will be restarted and re-spawned as usual.
