These kind of questions should go to the Learn section of the 
forum.
Also, what you are trying to accomplish is not exactly clear and 
the example code that you give doesn't compile without 
modifications.

One possible cause of your error is the fact that you send a 
tuple (tid + int) not a single int.

I tried to give a fixed version of your code that used 
receive(...) here:

You should also signal to the other process that it should stop 
looping and exit, otherwise an exception get thrown.
