The first plot attached shows 24 hours of Corner3 and other CPS In1s along with Lock state signals.

The two large spikes in the first half of the trend shows saturating spikes on the Corner 3 CPS and concurrently the BS Watchdog tripping.  These glitches only show on C3 and are on all four C# CPSs.  Not shown are earlier locklosses and BS Trips that JimW in aLog 37499 attributed to Corner3 glitching.

First action Jim performed was power cycling the satellite racks at the chamber.  Jim did this by unplugging the rack power cord.

After the first LL on this log's plot, Jim un- and re-seated the gauge boards in the satellite racks.

After the second LL at ~1740pdt, I power cycled the C3 interface chassis and reseated and tightened the power cord of the chassis.

There is a final lockloss on this plot around 6am pdt but there is no to little spiking of the CPS channels and certainly nothing of the WD tripping saturations seen earlier.

So, the 6am lockloss was not the CPS but only time will tell if things are completely cleared up.

I still plan to look closer at the glitching and locklosses here so there may be more.
