OOM in Jboss 5

[samavedulark]

Hi,

I am using Jboss 5.1.0

JBM 1.4.6

java jdk1.6.0_20

I am using topic configuration for storing the messages, there will be huge number of messages.

I am getting OOM, when i check the heap dump there were arround

80,999 instances of "EDU.oswego.cs.dl.util.concurrent.ConcurrentHashMap$Entry", loaded by "org.jboss.bootstrap.NoAnnotationURLClassLoader

In fact i am using Jboss cache also.

I just want know is there anything to do with JBM.

Thanks

Based on what you've presented, I don't see any evidence that JBoss Messaging is contributing to the OOME.

For future reference, community help for legacy platforms (i.e. JBoss AS 5.x and JBoss Messaging) is typically very weak since development is always focused on the leading edge of the code-base.  If you anticipate that you will keep an application installed for many years on the same components then I recommend you get a support subscription from Red Hat as they provide extended (up to 7 years) support for every platform they ship (in your case it would be EAP 5.1) which includes bug fixes for many of those years.

Hi Justin,

Than what would it cause for OOM and many instances of EDU.oswego.cs.dl.util.concurrent.ConcurrentHashMap$Entry.

Thanks
