Though this exception is infrequent and occurs sometimes but am wondering what could be cause of it.
Please note that broker and client communication is fine. client is able to send and receive messages on that topic but exception is continuously coming. There is no durable subscriber on this topic. Messages sent on this topic are non-persistent.
