the open question is whether or not the energy conditions apply
More precisely, whether they apply under conditions of extreme gravitational collapse. As I think I mentioned, certain quantum field states can violate the energy conditions; the question is whether the conditions encountered in extreme gravitational collapse would induce a kind of phase change that would produce such states. That's likely to remain an open question for a long time since that regime is nowhere near being accessible to our experiments any time soon.

That seems to be a quite exotic example. I'm not sure how seriously one should take that.
What you wanted to ask is whether there are more examples in nature of non-compliance with the conditions. The example I gave is within theoretical physics, as I said, and they are exact solutions of Einstein's equations.
