Network Rendering for Animation - Slaves drop out at the end of each frame

[eddiemg]

Using Network rendering for an animation, I have 7 slaves at 92 cores, and all slaves but one drop out completely for the last dozen or so tiles on each frame, leaving that one slave to finish rendering that frame. Then they all kick back in for the next frame. But it seems to be slowing down the render time. Any thoughts or suggestions on this?

Thanks
