> my activemq is a Cluster that has  three activemq single instance and using replicated stored levelDB .  when the cluster is running  for a long time ( a few days),    this situation is that JVM Old Generation is filled´╝îand eden and one of survivor 0 or 1 is filled.,  but not privider service and all of port include  61616 is dead when producer is calling.   this time three instance's process is running ,  about half an hour , zookeeper is selected and another instance start all port  and providers services
