You run out of AIO when you have more than MAX_AIO_SIZE * NumberOfOpenedFiles > 64k (The max-aio configured at OS level).

so.. increasing the default MAX_AIO_SIZE will get you to have a lower number of files.. not the opposite.

When you have more writes than max-aio, they will just wait on the executor until the queue is freed up. So I don't think that would be your case.

BTW: Better thinking now.. I think I should rename that parameter to something else such as AIO_QUEUE_SIZE.
