“The experiment process was killed” constantly

Hey guys,

I am running an experiment using version 3.2.5 and confronted a problem, that is, the experiment process was always killed suddenly during the experiment. I'm not sure what the problem may be. Anyone have an idea? Would really appreciate that!

Best regards,

  • Hi Neo,

    This happens if you click on the red 'Stop' button (new in 3.2) while the experiment is running. I don't see how you could get this specific message in any other way, because if the experiment crashes you should get a different error message. Are you accidentally clicking on the red 'Stop' button?


  • Hi there,

    I have the similar problem that averagely programme crashed 1 in 10.

    Here I attached my experiment file. I used 3.25 version (there is not image material in it, since I find I have too much image and fail to up load the osexp file, so I delete the image to make it small, but you can see my code).

    I find after around 15 times key press in the same trial, the refresh time become large, for example:

    [.......:xpyriment:79:WARNING] took 980.0 ms

    And some times it crashs.

    Any help can I get?

    Is crash because I put too much images?

    Appreciated any answers. @sebastiaan
