Increment queued failed requests by 2, instead of 1

* Unauthorized request retries are still incremented by 1 (retried in intervals of 15 seconds)
* Rejected request retries are incremented by 2 (retried in intervals of 1 hour)
* Max number of tries is 40

This will reduce the number of failed retries by an half.

When a new event arrives and the queue is full,
the event that is discarded is the oldest one and now the first one, with a FIFO logic.
