Please explain me the use of "Reselect on Service Down" and "Least Connection" and also which is better? Consider me new to this

Hi IheartF5,

Yes, I am running Adobe CQ 5.6 and currently using Round Robin algorithm. I am also not sure why this imbalance in request traversal is happening and I just saw the logs and was baffled to see that monitor status of one of the publisher kept on oscillating up & down every few seconds.
