We need to ensure that only when the connection is successfully inserted into the connections map can the handler send fd to notify the reaper to recycle the connection. Otherwise, the handler may have been executed and sent fd to notify the reaper to recycle the connection, and the connection has not been inserted into the map. Then the reaper cannot find the corresponding connection after receiving the fd, and loses the opportunity to recycle the connection, causing fd leakage; Signed-off-by: Fupan Li <[email protected]>
