      Description

      I have a simple thread that monitor remote wildfly process status. After some time client fails. Wildfly server also eat all memory and reports about connection errors. Some times wildfly also fails with fails with OutOfMemory exception.

      Client code:

      package ru.kamis.tests.xniomemoryleaks;
      
      import org.jboss.as.controller.client.ModelControllerClient;
      import org.jboss.as.controller.client.helpers.Operations;
      import org.jboss.dmr.ModelNode;
      
      public class OutOfMemoryDemo {
      	public static void main(String[] args) throws Exception {
      		
      		for(int i=0; i<1000000; i++) {
      			ModelControllerClient client = null;
      			client = ModelControllerClient.Factory.create("localhost", 9990);
      			
      			ModelNode operation = Operations.createReadAttributeOperation(new ModelNode().setEmptyList(), "server-state");
      			client.execute(operation);
      			
      			client.close();
      			
      			if(i % 1000 == 0) {
      				System.out.println("Processed: " + i);
      			}
      		}
      	}
      }
      

      Client output:
