Stopping a task ¶
As was explained above, a task is marked as being executed while it is running. If the process running the task crashes or is killed for some reason, the task will stay marked as being executed. This will be cleaned up automatically according to the maximum lifetime parameter (also described previously), but this may be inconvenient in some circumstances.
In such cases it is possible to use the “stop” button to clean up marked executions for the given task. This will make it possible to run this task again. However please note that this will not kill a corresponding still running or continuously hanging process.
