-These are messages from a *remote* go-libp2p peer (likely another Kubo node) with the resource manager enabled on why it failed to establish a connection.

 You can distinguish resource manager messages originating from your local node if they're from the `resourcemanager` / `libp2p/rcmgr_logging.go` logger
 or you see the string that is unique to Kubo (and not in go-libp2p): "Protected from exceeding resource limits".

 ### How does the resource manager (ResourceMgr) relate to the connection manager (ConnMgr)?
 As discussed [here](https://github.com/libp2p/go-libp2p/tree/master/p2p/host/resource-manager#connmanager-vs-resource-manager)
