    JMX Wildfly 8.2.0 Final




      Last week I managed to configure monitoring Wildfly 8.2.0 Final thrue JMX with Zabbix java gateway.  After 3 days of monitoring Wildfly used all Heap Memory and hanged. After restart everything was normal, all application was working normal. And then after 3 days again same problem Wildfly used all Heap Memory. In server.log I get error:

      2014-12-05 06:47:32,970 ERROR [io.undertow.request] (XNIO-1 I/O-2) Undertow request failed HttpServerExchange{ GET /}: java.lang.OutOfMemoryError: Java heap space

      2014-12-05 06:50:19,636 ERROR [stderr] (Remoting "oraprod01:MANAGEMENT" task-1) Exception in thread "Remoting "server1:MANAGEMENT" task-1" java.lang.OutOfMemoryError: Java heap space

      It loks like that JMX requests are filling memory, and Wildfly does not releasing memory as you can see on Zabbix graph used Heap Memory is growing slowly :


      I came across same behavior with Jboss 7.1.1.

      Is this known problem with JMX?


      Thanks and best regards!
