I use tigase (version 5.3 built by myself),and I sometimes find that some message sent from user A to user B would lead to a new message sent from User B to User A with the same body while User B did not send it.

We need a bit more details on the problem than this. Ideally we would like to see packets sent and received by both clients.
The only think which comes to my mind is that a message from A to B could not be delivered for some reason and was sent back with an error message.
