As Krishna noted in aLog 35160, this machine does not have a lot of extra juice to run this. I should have closed out before but was watching the diagnostics. Jim turned off the sensor correction so in case the session closing glitched things, it would not glith the ISI/IFO. It did not and SC has been turned back on.
I've attached about 10 hours of BRS-Y driftmon data around the time of this crash. It looks like this crash was caused by trying to use BRS-Y in a bad range. Even if the data looks temporarily smooth, BRS-Y should not be used if driftmon is below -15k counts.
The close time association with closing of the remote desktop terminal was likely just a coincidence. It is still advised to not login to the machine remotely when BRS-Y is being used for feedforward, unless really necessary.
