Hi guys,

Periodically in debug logs we can see:

```
[2019-10-20T18:07:48,342][DEBUG][o.e.a.a.c.n.t.c.TransportCancelTasksAction] [node-00] Received ban for the parent [s8jcicF9TDy_iIzFgH07zw:10741071] on the node [A9AdXLb5QA-ZMcicCn26OQ], reason: [by user request]

```

In this time network traffic temporary is decreased

Hi @Denis_Lamanov

Those logs mean that the node received cancellations for the given tasks.  
Since the task had child tasks, a ban for the task was set on the node, which is basically just a flag that prevents any of the tasks children from executing. (see code in the `TaskManager` class for details if you're interested)
