      Description

      We add JCIFS Monitoring at 21 Nov 3:45pm and do a OpenNMS restart.
      We see a continously increase of java threads since this restart.

      At Nov 23 1:16pm OpenNMS crashed with "java.lang.OutOfMemoryError" and we get a heap dump.

       

      Only two servers become the CIFS pollers with different services:

       

            <service name="CIFS-Customer-Software" interval="30000" user-defined="true" status="off">
         <parameter key="retry" value="1" />
         <parameter key="timeout" value="3000" />
         <parameter key="domain" value="DOMAIN" />
         <parameter key="username" value="opennms-user" />
         <parameter key="password" value="password" />
         <parameter key="path" value="/customer-software/" />
         <parameter key="mode" value="path_exist" />
      </service>
      <service name="CIFS-Xchange" interval="30000" user-defined="true" status="off">
         <parameter key="retry" value="1" />
         <parameter key="timeout" value="3000" />
         <parameter key="domain" value="DOMAIN" />
         <parameter key="username" value="opennms-user" />
         <parameter key="password" value="password" />
         <parameter key="path" value="/xchange/" />
         <parameter key="mode" value="path_exist" />
      </service>
	  
   <monitor service="CIFS-Customer-Software" class-name="org.opennms.netmgt.poller.monitors.JCifsMonitor" />
   <monitor service="CIFS-Xchange" class-name="org.opennms.netmgt.poller.monitors.JCifsMonitor" />
