Hi experts, We have a cluster with 10 nodes which used to work very well. Recently, the cluster become unstable, after some debugging, we found that JVM can go into an unstable state some times without obvious load. JVM heap usage will go up very quickly and trigger heavy GC and then go back again…

Frequent GC brings down cluster without obvious load
