in-memory federation transaction transmission queues build up indefinitely for offline servers #7828
Description
when a server is offline, any events that we would have sent to it stack up in memory indefinitely.
See, for example, this graph for matrix.org:
Apart from the memory usage concerns, this means that if a server goes offline for 1000 events, then when it comes back we will try to send it all those 1000 events in turn, rather than just sending it the most recent ones in a room.
