[aaron, rana]

While going to take some transfer functions of the MC WFS loop, LSC was down. When we tried to restart the FE using 'rtcds restart --all', c1lsc crashed and froze. We manually reset c1lsc, then laboriously determined the correct order of machines to reboot. Here's what works best:

on c1lsc:

rtcds start c1x04 c1lsc c1ass c1oaf c1cal c1daf

Starting c1dnn crashes the other FE

on c1ioo

rtcds restart --all

on c1sus

rtcds restart c1rfm c1sus c1mcs

restarting c1pem crashes the other FE on c1sus

We're seeing a lot of red IPC indicators--perhaps it's an issue with the order we're restarting?
