This commit implements an upper limit on the number of batches that may be waiting on a queue for processing. Once the limit has been reached, the oldest batch is dropped from the queue and an error message is logged. The maximum number of batches that can be waiting on a queue is configured through the max_queued_batches parameter of the queue, which defaults to 100 and can be globally overriden with the max_queued_batches parameter in kong.conf
A more complete rewrite of the queuing system is in the works but will not make it into 3.2.
