Android Client not able to recive File if it has already send a file

I have posted this question in the openfire discussion forum.....

But i think is issue is with the implementation of asmack File Transfer so i am posting it here....

The Issue I am facing is that:

let Client A sends a file to client B. Client B receives what client A send.

Now, if client B or client C sends any files to client A, client A is not able to receive Files. But client B can send a file to client C.

The isuue is if the android client sends a file then the client is not able to recive file......
Please Guide me with the implementation of file transfer....
I am using asmack-2010.05.07.jar and openfire3.9.3

The Implementation and the error log are in these posts so iam not rewritting it here......
