Unfortunately this is a downside of CouchDB. If a document merge is already in progress when your uploaded packet arrives, your packet will be rejected (I think with 409 Conflict). This already documented, and CouchDB behaves in this way so it can be used as a distributed database if required (it isn't for habitat).
As the docs say, if you receive a Conflict you should retry. For instance, dl-fldigi does this.

Indeed, the habitat python client does it too:

Thanks for the explanations. Indeed the windows tracker uses the python client. M0RJX is trying to take care of the LoRa part for repeating messages after being rejected I noticed.
Topic can be closed, big thanks for the great support !
