[systester][1.5.1] Errors count separate from failure time?
 

I'm doing burn-in/test with all cores of my CPU. There is something in the UI I don't understand.
It constantly says: "Errors: 0", but occasionally it will display in the "Failed after" section a time (e.g. "4s").
Is this an internal error of the program (and not a failed test)? I am running the GUI and switching in and out of the program.
Or is this indeed a negative test result, and it just doesn't add it to the counter?
CPU temperature is reported as normal. RAM is tested. Also it seems to be doing more "turns" than I had specified.
