style="font-family:"Courier New"">Hi Guillaume,<br>
<br>
Indeed, a weird one, not marking the destination as failed
upon failure to ping it. I checked the drouting module and
it is doing such disable, so it might be a overlook in the
dispatcher module. Please open a bug report on the github
tracker, so we can address this issue.<br>
