Symptoms

You have a four (4) node cluster and have configured the Default Load Algorithm to be weight-based (the default is round-robin).

It is observed that node 1 was taking most of the active sessions. After changing from weighted-based to round-robin, it was noticed that the active session on each node increased and were more balanced; however, most of the active sessions continue to be on node 1.

Your goal is an even weighted distribution across all nodes.
