> Similar to regular state transfer streaming state transfer protocol maintains a list of state requesters. As state response is sent to requesters these entries are removed from the list. However, in highly concurrent scenarios where dozen of nodes are started and request get-and-state transfer state requesters entries in the list are filled up and as the list is iterated *multiple* state responses might be sent to state requester. 
> This behavior is not usually noticed by users as a bug but should be fixed anyhow.
