https://forum.cloudron.io/topic/13408/update-to-cloudron-8.3-error We get a Task xx crashed with code null in the notification. The crux of the issue is that we use KillMode=control-group. This ends up sending SIGTERM signal to box code and all the sudo in parallel. The box code then sees the sudo die and records the task as failed. To fix, we switch to KillMode=mixed. This gives box code a chance to handle SIGTERM first. It cleans out its task list and kills all the sudo.
