title: Hazelcast Logging 70% threshold Message with out adding anything to map
body: <p>I am using hazel cast in a 2 node cluster following is my configuration:</p>
  
  <pre><code>&lt;hz:hazelcast id="hazelcast_instance"&gt;
          &lt;hz:config&gt;
              &lt;hz:instance-name&gt;hazelcastinstance&lt;/hz:instance-name&gt;
              &lt;hz:group name="cluster" password="asdfg" /&gt;
              &lt;hz:properties&gt;
                  &lt;hz:property name="hazelcast.health.monitoring.level"&gt;SILENT&lt;/hz:property&gt;
  
              &lt;/hz:properties&gt;
              &lt;hz:network port="5710" port-auto-increment="false"&gt;
                  &lt;hz:join&gt;
                      &lt;hz:multicast enabled="false" multicast-group="224.2.2.5"
                          multicast-port="54327" /&gt;
                      &lt;hz:tcp-ip enabled="true"&gt;
                          &lt;hz:members&gt;${cluster.hzmembers}&lt;/hz:members&gt;
                      &lt;/hz:tcp-ip&gt;
                  &lt;/hz:join&gt;
                  &lt;hz:interfaces enabled="false"&gt;
                      &lt;hz:interface&gt;192.168.1.*&lt;/hz:interface&gt;
                  &lt;/hz:interfaces&gt;
              &lt;/hz:network&gt;
  
  
              &lt;hz:map name="cluster.map" max-size="100" max-idle-seconds="55"
                  time-to-live-seconds="55"  eviction-policy="LRU" eviction-percentage="50"/&gt;
          &lt;/hz:config&gt;
  
      &lt;/hz:hazelcast&gt;
  </code></pre>
  
  <p>I am just using the map to check the partition , so that i can run only one instance of batch in a cluster:</p>
  
  <pre><code>hz.getPartitionService().getPartition("cluster.map").getOwner().localMember()
  </code></pre>
  
  <p>But time and again in the log i see messages like</p>
  
  <pre><code>[cluster] memory.used=1.8G, memory.free=583.9M, memory.total=2.4G, memory.max=2.4G, memory.used/total=76.07%, memory.used/max=76.07%, load.process=-1.00%, load.system=-1.00%, load.systemAverage=13.00%, thread.count=147, thread.peakCount=158, event.q.size=0, executor.q.async.size=0, executor.q.client.size=0, executor.q.operation.size=0, executor.q.query.size=0, executor.q.scheduled.size=0,
  </code></pre>
  
  <p>Not sure what is filling up the hazelcast cluster memory.</p>
  
  <p>Any dvice will be highly appreciated.</p>
  
  <p>I am using Hazelcasr version 3.1.7</p>
