re-occurence of ALS glitches

We had another incident of ALS glitches today, this time in the X arm. We sat for a while just with the green arms locked, and the glitches became more frequent and worse and then things got better.  The glitches were bad for about an hour and a half, but you can see that something is still noisier than it was this morning. 

We have had this problem several times before: 22184
