Hi: Unfortunately I don't see anything in the exception that implies that this is caused by Java itself. Really we need to understand from the JBoss code what the potential causes of the invocation exception are.

Visualize JVM GC log data
Published (2009-11-24 16:38:00)
You're correct except that Splunk can index any kind of data. GC logs is just one kind of input. Imagine correlating something on your WAS tier to JVM performance, etc. Good for adhoc investigations and the like. Or even doing alerting based on the data.

Hi, Have a look in the Javacore file, the stack trace from the "Failing Thread" section should point to the method that is trying to allocate the large object. With any luck this should help you pin it down. Ben Hardill

You should be able to download AIX JDK from IBM developerworks site. For Windows it would be bundled with the application like Websphere if you have license for one. How did you get your earlier version of IBM JDK for JAVA6 on Windows ?

I've thought a while about my questions... and got to idea that I don't necessarily need anonymous inner classes... I just need to generate new classes according to the annotation and then use them in modified methods. So I think I can do everything at bytecode level (if a tool can generate new classes, overriding methods). Could you suggest me what tool is better for my problem? ...

Hi, It's much more likely that it's is class objects or dosed objects that are driving the fragmentation than objects a would be allocated from the pinnedFreeList. You should ensure that -Xk is set to the correct size to collect the class files together in a single cluster at the base of the heap. You can feed the heapdump you have through the tool on this page: http://www...

Hi, The following is taken from the IBM 1.4.2 Java Diagnostics Guide -Xverbosegclog:<path to file><filename> Causes verboseGC output to be written to the specified file. If the file cannot be found, verboseGC tries to create the file, and then continues as normal if it is successful.
