BRSX C code crashed over break, running again now

I wanted to try restoring the controls configurations of all of the ISI, so I changed the SEI_CONF manager to windy, which caused the EX configuration node to complain about the state of the BRSX. When I opened the BRSX overview, the driftmon was railed at -16k. I logged onto the beckhoff machine and found the C code dead. Looking at time series for the driftmon and cbit it looks like BRSX started getting glitchy, then the C-code crashed on New Years Day. Not sure what happened, but the spikes on the driftmon channel kind of remind me of what happens when someone stays connected the the beckhoff machine and walks away for a couple days. Something also seems to repeatedly ring the BRS up, maybe a result of some code mini-crashes? I don't know, weird stuff. I'm filing an FRS to track this.
