Could this be the related to NET-412 ?

> I am using commons net 2.0 version. I have a TFTP server implemented and the scenario is below - 
> 1) Client sends TFTPWrite request.
> 2) Server sends DATA packet, client sends ACK. Server receives it (thr TFTP.receive()). 
> 3) This goes well for quite some time.  
> 4) Now server gets same ACK thrice, means some packets are not reached to client and client sends the same ACK again. 
> 5) Server also sends the old DATA packet coresponding to the ACK, using TFTP.send(). But somehow those DATA packets are not seen on the interface in the snoop log :(. So client has a timeout of say 5 secs, and closes the connection at its end indicating overall transfer failure. And I could see the DATA packet coming in the snoop log after 13-14 secs of delay :(, once TFTP.send() is invoked. 
> This does not happens always. Scenario works fine most of the times, but there are cases where it's delaying sending the packet on the i/f. And delay osberved was around 10 secs. Because of this, Client closes a connection :(.
