Thank Igor, But the problem remains the same. Just to give more clarity. I am doing load testing on 2 cache keys, with almost 500 Hits per second which includes get, put and remove. So when I start with 1 server and my clients, it works fine, but when I try to add more nodes to my cluster, my initial node fails.
