I have AF set to run at sequence start, but the last couple of nights I have run AF manually just before starting the sequence. When the automatic AF came up I canceled it (clicked the Cancel button) to skip it.
Even though I canceled it manually, SGP sends an alert through the notification system:
Auto focus received a bad HFR value 3 times in a row! Something may be wrong!
The alert text is a bit misleading, and is not necessary since I explicitly canceled the AF.
This is easily reproducible.
Here is where I cancelled the AF:
[2/3/2016 7:11:31 PM] [DEBUG] [Camera Thread] Handling monitoring event (Text File 1, Warning): (m31_ha) Auto focus received a bad HFR value 3 times in a row! Something may be wrong!
