Multiple threads are using the same connection when the connection dies. All the threads race to restore the connection, potentially, reconnecting multiple times.
Solution
Put the connection behind a RwLock, acquire the writer lock, check if the connection is closed via is_closed method, if it is, reconnect. This way the reconnection happens at most once.
