Lost lock about 45 minutes ago. Struggling to recover right now. First, it was dying at DRMI, but after a while I had a new issue with ALS, where the ALS-TRX arm power wasn't very good. I found an alog saying something about "reset VCO" but the log didn't say which one or how. There are 4 on the ALS overview, two of which said something about having run out of range. ALS-X guardian also complained of "VCO" and "PDH", with no more detail. After I got brave and reset "all" (2) the VCOs, the Y-arm ALS then wouldn't lock, so I had to touch up PR3 to build up ALS COMM. I'm now back to where I was right after the lock loss, waiting to survive DRMI lock.
