[JBoss JIRA] (AS7-6254) Memory leak caused by retained connection ids in RemotingConnectorServer superclass
by Taras Tielkes (JIRA)
[ https://issues.jboss.org/browse/AS7-6254?page=com.atlassian.jira.plugin.s... ]
Taras Tielkes updated AS7-6254:
-------------------------------
Affects Version/s: 7.1.3.Final (EAP)
> Memory leak caused by retained connection ids in RemotingConnectorServer superclass
> ------------------------------------------------------------------------------------
>
> Key: AS7-6254
> URL: https://issues.jboss.org/browse/AS7-6254
> Project: Application Server 7
> Issue Type: Bug
> Components: JMX
> Affects Versions: 7.1.1.Final, 7.1.3.Final (EAP)
> Reporter: Taras Tielkes
> Assignee: Stuart Douglas
>
> We're running 7.1.1, with a patch applied for REMJMX-45 to limit the worst leaks coming from the JMX subsystem.
> However, even with this patch applied we can only survive for a few days in a production-like scenario.
> It seems that {{org.jboss.remotingjmx.RemotingConnectorServer}} never calls the {{connectionClosed()}}/{{connectionFailed()}} methods in its superclass.
> As such, the connection ids that are stored in the field {{javax.management.remote.JMXConnectorServer#connectionIds}} are never released.
> Given sufficient connections made to a running instance of 7.1.1 (for example, various monitoring tools), an out-of-memory end-state is inevitable.

[JBoss JIRA] (AS7-6254) Memory leak caused by retained connection ids in RemotingConnectorServer superclass

Taras Tielkes commented on AS7-6254:
------------------------------------
Note that this issue is still present in 7.1.3 EAP.
Steps to reproduce:
1) Install clean 7.1.3 JBoss instance
2) Add JMX user using the provided admin script
3) Run a client that repeatedly creates a JMX connection (using the {{service:jmx:remoting-jmx}} protocol, using the provided {{jboss-client.jar}} library)
After sufficient time, depending on the configured heap size, you'll see the JBoss server JVM run out of memory.
I have an {{hprof}} heap dump that shows the leak reproduced by the steps above. If you're interested in looking at that, let me know where to upload it.
