While putting the system through the load of 9K users with each user modifying the state every 10 sec found that there is sharp increase in amount of memory being consumed by the process. After few hours process raised out of Memory from old generation. Memory histogram of the process shows following two classes taking lots of heap space.   1:       7023853      224763296  java.lang.ThreadLocal$ThreadLocalMap$Entry    2:       7022005      168528120  java.util.concurrent.locks.ReentrantReadWriteLock$Sync$HoldCounter I’m have 3 nodes in cluster. I’m using async replication and my configuration file is as follows:- Any help will be highly appreciated.
