We need to ban unpredictableSeed from unit tests. We should NOT be having random failures due to actual intentional randomness. I don't care how low the probabilities of failure are. Any failure is going to be treated as a failure, even if it's a low probability failure.

I haven't seen this one in the last two years, so I'm assuming that it has been fixed. Closing.
