We found this afternoon that our problem with ALS glitches is actually due to a frequency crossing of the DIFF VCO.  We were able to reproduce the glitches with the Y arm blocked by moving around the control voltage out of the DIFF PLL.  Removing the DIFF FDD has no impact.  

We have locked ALS twice by first locking ALS_DIFF, then locking COMM.  (It used to happen in the other order.)
