In #9976 the example shows saturated when both are equal:

{
  "queueMaxSize": 200,
  "queueFillCount": 200,
  "queueSaturated": true
}

There is something bogus here :)

The code is:

  lazy val queueSize = AtomicInt(0)
  ....

  def queueInfo() {
    ...
    val current = queueSize.get
    val saturated = (current+1) >= maxQueueSize
    val code = if(saturated) HttpStatus.TOO_MANY_REQUESTS else HttpStatus.OK
    ...
  }

  ...
  // see if you can add a file
  val canDo = synchronized {
    if(queueSize.incrementAndGet(1) <= maxQueueSize) {
      // the decrement will be done by the report processor
      true
    } else {
    ....

So for maxQueue = 50, in info, current queue = 49, +1 = 50 >= 50 => "saturated".
In canDo, current = 49, incrementAndGet(1) = 50 <= 50 => true
