Got this issue out of nowhere. Saved logs in support_bundle.zip
Restarting edge fixed it.

Expected Behavior

No errors, as I am not doing communication with devices, only receiving telemetry.

Current Behavior

2021-05-13 07:01:51.477 0100DA30: LoRaTools.Mac.MacCommandException: The Mac Command was not well formed, aborting mac command processing

Hello @maxstefaniv

Thank you for raising the issue. I managed to isolate the message triggering the behavior. This is a particular malformed message that doesn't follow the lorawan specs.
Due to a missplaced catch clause in our code, we kept processing the message indefinitely. This is now fixed. We will release a new version in the next days encompassing all these fixes.

Should the problem happen again feel free to reopen the issue
