Subject [jira] [Comment Edited] (AMQ-4889) ProxyConnector memory usage skyrockets when several ssl handshakes fails
Date Mon, 02 Dec 2013 08:40:38 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836369#comment-13836369

------------------------------------------------------------

Still an issue in long-term memory consumption due to another bug in ProxyConnector: missing
equals and hashCode methods in ProxyConnections induced a memory leakeage in connections collection
inside ProxyConnector.

I added another patch to solve also this issue.

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.8.0, 5.9.0
>         Environment: Seen in Windows 7 64bit, Windows Server 2008 R2 and Linux RHEL 6.3
64 bit

> See [nabble|http://activemq.2283324.n4.nabble.com/Proxy-Connector-memory-consumption-td4674255.html]
for further details.
> To reproduce the issue:
> # Start embedded proxy broker and the AMQ broker that are embedded in *AMQTestBroker*
project (see attachments);
> # Start the *AMQTestConsumer* project; This program repeatedly tries opening a connection
to the ProxyConnector with wrong certificates.
> # Open jconsole to monitor AMQTestBroker memory usage: you should experience an OOM error
within one hour with the suggested settings (Xmx = 2048m).
> Launch configurations and test keystores are attached to this issue along with the java
projects.
> This behavior seems to affect _ProxyConnector_ only, running the test against a standard
nio-based _TransportConnector_ does not seem to produce anomalous memory consumptions.
