[jboss-jira] [JBoss JIRA] (AS7-4904) Memory leak when requesting attributes using JMXConnectorFactory over remoting-jmx via management interface

    [ https://issues.jboss.org/browse/AS7-4904?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12703578#comment-12703578 ] 

Mattias Holmqvist commented on AS7-4904:
----------------------------------------

After profiling, we have found a HashMap in [1] that only holds references to proxies with RemoteConnectionChannel and RemoteConnection objects, without either using or removing them. This is causing a memory leak since these connections will be references forever in the HashMap.

We have a pull request [2] to plainly remove the HashMap since it's not used and causing JBoss to go down when we monitor it over JMX.

> Repeated remote request of JMX attributes, as performed by a Nagios plugin, causes heap space to grow to the limit and eventually the server to freeze.
