Java thread tech question

Just asking, to gain some knowledge from experts and food for thought

Given a scenario that singe thread that communicates between system A and B .. for some reason thread hung and stopped communicating to system B

How do you analyze the issue ?

Take thread dump , heap dump and analyze.

As you know thread does unit of work and it is part of processor , involves CPU scheduling and some kernel (low level details) .. there may be possibility that thread hung up is not application specific, may be some kernel level ..

What you do in this case , how do you address the issue , as work around you can restart application but it takes time . Is there way we can find why thread hung up ? Here the restriction is there should be only one thread for communication.
