Yes, that seems to be the case.

The shovel status still shows as running on this point. I checked the logs and
couldn't find anything (I have no idea exactly when the shovel disconnects).

I have attached the logs in case they might be of help.

OK, so if I understand correctly after you restart rabbit1 or rabbit2 the shovel
plugin stops sending ack after consuming from the source queue, right?

Mhm.  Again, what does the shovel status show?  The logs would be useful as
