Subject [jira] [Resolved] (AXIS2-5310) Axis2.0 : 1.6.2 : Memory Leak Issue
Date Mon, 30 Apr 2012 17:29:48 GMT

     [ https://issues.apache.org/jira/browse/AXIS2-5310?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andreas Veithen resolved AXIS2-5310.
------------------------------------

    Resolution: Not A Problem

The conclusion given in the description is not correct. Please note that it says "probable
memory leak". Tomcat's leak detector is far from perfect. In this case:

1. org.apache.axiom.util.UIDGenerator$1 doesn't cause a class loader leak because the value
of that thread local is of type long[]. See http://code.google.com/p/arit/wiki/ThreadLocal
for more information. Note that previous Axiom versions indeed caused a class loader leak,
but this has been fixed; see AXIOM-354.

2. The thread local storing the org.apache.axis2.context.MessageContext is cleared when the
request has been processed. This doesn't occur because as shown by the previous error message,
"The web application [...] is still processing a request that has yet to finish". This is
generally caused by bugs in application code, not in Axis2. If you believe that there is an
issue in Axis2 blocking the request, then you need to provide a thread dump that shows this.

> Mon, Apr 30, 16:08:29;$Z0QF;SEVERE;WebappClassLoader#clearReferencesThreads;The web application
[/PSAPI-V1-0/axis2] is still processing a request that has yet to finish. This is very likely
to create a memory leak. You can control the time allowed for requests to finish by using
the unloadDelay attribute of the standard Context implementation.

web application [/PSAPI-V1-0/axis2] created a ThreadLocal with key of type [java.lang.ThreadLocal]
(value [java.lang.ThreadLocal@2465e5]) and a value of type [org.apache.axis2.context.MessageContext]
(value [[MessageContext: logID=3fecb85757bee1e6fd9cdc8eb6a0e146d5c1eaa7dd28d0e7]]) but failed
to remove it when the web application was stopped. Threads are going to be renewed over time
to try and avoid a probable memory leak.
