Not really, all these things are pretty unlikely. But if you deploy enough installations and run them with enough load you are pretty much guaranteed to see all the issues, even if only rarely. There will be someone simply killing no longer needed threads rendering a log buffer unusable from time to time. Someone will from time to time send relatively huge messages making the starvation scenario more likely. The thread won't of course starve forever but just hitting the rotation twice will make for a pretty heavy outlier in the latency chart.
And just in case I wasn't clear about that, I am looking at all of this from a pretty theoretical point of view - I have at best a very rough idea what this will be used for in the real world and what scenarios are important and likely and what just doesn't matter. Actually maybe even the thing I just wrote is nonsense because nobody in your target audience will simply kill threads, but then again developers are notoriously good at bending and ignoring rules.
