The scheduler collapse problems in R15 and R16 are widely known and not resolved. Frankly, as developers of a database, we should strive to provide end users with the most reliable and best experience, which in my opinion means we should recommend R14B01. There is not a battle tested, reliable version of Erlang that has proven to solve the scheduler collapse problems, and until that time, I think it's unwise to remove support for R14.
