The students get ejected from the course. This kept happening with the Text Reconstruction exercises (WebRhubarb) because they generated so much server traffic in the Hot Pot Module version. This doesn't happen in the QuizPort version to my great relief - at one point I feared I might have to rewrite the course or face a student rebellion.
Now, it's all fine thanks to the wonderful QuizPort Module.
Cheers,
