Hi Adam,
Sorry for the delay (quite busy at work), but I do have some testing results.
When the error occurs, the status page displays no traffic flowing through the adapter (the bandwith column remains 0). Also see attached screenshot. The log shows errors similar to above (graceperiod expired messages).
However, when I briefly disable the adapter on the adapter page, and enable it again, the channel starts streaming after about 2 seconds from that adapter. This method resolved it about 4 times successfully when the issue occurred.
The log file information:
