Resolution:
The column "S" when we do "show connections" which  indicates if the connection is started or not.
In some cases, the connection will go from "+" (started) to "-"  (stopped) when the server has more
than 8MB of pending data for that  connection. By pending here means,  the data was sent to the client,
not just pending on the destination. If the change is transient, there  is nothing to worry about. It can
happen because messages sent to this  connection are big and the consumer does not consume
them fast enough. However, if the situation persists and is seen as the message not being
consumed anymore, careful review of the application logic/log should be  done. It is possible for
instance that a Java application had an  OutOfMemory error which then results in stopping to drain
data from the  socket.
