I found that recently I get my slaves telling me "receiving job but currently busy with another job" so they don't render with. Only solution is to restart the slave.
This happens frequently if I did a RT GPU render then follow that with a RT cpu or bucket render.
So, my guess the RT GPU don't release the DR slave after the render has been stopped by the master.
