Maybe this helps you, maybe not, but can't hurt to try. When you're switching between talkers and listeners make sure that roscore and all ros nodes are shutdown, and then restart the nodes you want in the machine you want. Nodes can get disconnected from roscore if things are starting and stopping and roscore gets shutdown and restarted while nodes keeps running.
