We've had multiple collisions with uuid v4. I'm not overly familiar with the examples, but in one case, the collision was found because the collision happened in the same account! Customer: "Why do these two events have the same id?" Us: "Wow." I think we determined that it was a limitation in the random number generator in the Perl lib we were using. To avoid that, I believe the solution was to go with uuid v1 plus a nonce of some sort.
