[jboss-jira] [JBoss JIRA] Commented: (JBAS-5345) New instance of resources injected on every onMessage MDB call

[Martin Husted Hartvig (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-5345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12430942#action_12430942 ] 

Martin Husted Hartvig commented on JBAS-5345:
---------------------------------------------

I'm having the same problem and tried to use the StrictMaxPool to handle it. Using JProfiler indeed shows that the bound on how many MDB that may be alive is correct, but what is problematic is that the number of resource instances keeps increasing, just like Dok Tora describes.

Using 4.2.2. GA, I looked in the changelog of 4.2.3. GA and it doesn't look as you made changes regarding this issue.

As I see it the provided workaround doesn't solve the problem. 

We have this running in production and memory is slowly been eaten which, if we don't restart JBoss from time to time, ends with an OutOfMemoryError. I would very much like to see this issue reopened.
