  "message": "The \"worker_aio_requests\" directive.\n\nThe default value is 32 AIO simultaneous requests per worker. Previously\nthey were hardcoded to 1024, and it was too large, since Linux allocated\nthem early on io_setup(), but not on request itself. So with default value\nof /proc/sys/fs/aio-max-nr equal to 65536 only 64 worker processes could\nbe run simultaneously. 32 AIO requests are enough for modern disks even if\nserver runs only 1 worker.\n",
