What is happening?

I've only seen in 2 tests so far but seems like sometimes the test/logs gets stuck, you can see the test took 30 minutes but if you look in the log, it only shows a few minutes worth of logs before it cuts off. It's unclear to me if the test got stuck or if the logs stopped being collected or what.
