> When a new {{IncomingStreamingConnection}} is created, [we register it in the connections
map|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/net/MessagingService.java#L1109]
of {{MessagingService}}, but we [only remove it if there is an exception|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/net/IncomingStreamingConnection.java#L83]
while attaching the socket to the stream session.
> On nodes with SSL and large number of vnodes, after many repair sessions these old connections
can accumulate and cause OOM (heap dump attached).
> The connection should be removed from the connections map after if it's finished in order
to be garbage collected.
