AP1100AE, while tracking/guiding "Motor Stall"


ap@CaptivePhotons.com
 

I was imaging and it was going great, guiding in the 0.18 to 0.25 or so range, all was well and I glanced at the screen and saw stars streaking.  APCC was showing tracking=0.  I reached over and clicked on the status bar to start it tracking (NINA at the time was doing a plate solve to recenter since it knew there was an issue).   NINA completed the plate solve and slewed to recenter, and continued running. 

Meanwhile I saw the pink Comm Events, clicked it, and there are a bunch of Motor Stalls show over a four seconds.  After I clicked to start tracking NINA centered, and it is once again guiding.

I went outside to check -- nothing was caught (nothing anywhere near anything that could catch), no visible issues.  It's carrying all of about 25 pounds with a TV101is, and I carefully balanced before starting.  It was not near meridian (about 75 minutes until) or any limit. 

If it's useful I can send logs, etc. but below is the apcc log just before and after the first stall, and also ascom.

Am I looking for a hardware issue, some kind of software thing, or what?   This is V1.9.1.3, the beta that was sent out, running with PHD2 (2.6.10) and NINA (1.11 # 171).   I'm not about 20 minutes later no further events.   CP4 -> Mount is ethernet. COM31 is virtual for ASCOM to NINA and PHD2. 

What should I be looking for?  

And is the normal reaction to a motor stall to set tracking to zero (It did not park or disconnect).
