[JBoss Messaging] - Threads not being cleaned up when clustered

by chip_schoch

Clustered App servers. JBossAS 4.2.2.GA, JBM 1.4.0SP3 -------------- | | Appserver1 | <====== ConvServer1 | | Appserver2 | <====== ConvServer2 | -------------- | My configuration is a shown above. I have 2 linux JBoss servers clustered and two windows jboss servers not clustered that act as clients to the clustered queues on the app servers. The conv servers connect using the ClusteredXAConnection factory. When I run a bunch of messages through in this configuration the thread count on both appservers continually increases until eventually I run out of memory. When I shut down one of the app servers and perform the same test the thread count on the other app server decreases initially then remains steady . It does not increase when I run a bunch of messages through it. -------------- | | | <====== ConvServer1 | | Appserver2 | <====== ConvServer2 | -------------- | DevApp1 ThreadCount DevApp2 ThreadCount | Cluster with queuing started on devapp2 | Start 158 200 | After 4 usign packages 167 206 | After 4 usign packages 173 208 | After 4 usign packages 179 208 | After hundred events 177 212 | After 10 WPS packages 178 212 | After 10 WPS packages 180 212 | | DevApp2 Only | | Before shutting down Devapp1 212 | After shutting down DevApp1 187 | After 4 usign packages 187 | After 6 usign packages 187 | | Restarted with each conv server | connecting to different appserver (no message sucking) | | Start 155 225 | After 4 usign packages 169 228 | After 4 usign packages 174 232 | After 3 packages one at a time 175 235* | After 20 uSign packages 187 256 | | Without belaboring the point, in our system a package causes a series of messages to be posted to various queues as it moves through the processing chain. The packages called usign require that a conversion be performed by a service running on the windows (conv) servers. These are the ones that cause the increase in the thread count. I am convinced that it is not my code that is leaving the threads around because it only happens when the cluster has more than one server running. * I observed that appserver one processed the message, but the thread count increased on appserver2 anyway. Here are a couple of the stranded threads from the jmx-console view. Thread: Thread-1562 : priority:5, demon:true, threadId:4470, threadState:WAITING, lockName:java.lang.Object@11bad13 | | java.lang.Object.wait(Native Method) | java.lang.Object.wait(Object.java:474) | EDU.oswego.cs.dl.util.concurrent.LinkedQueue.take(LinkedQueue.java:122) | EDU.oswego.cs.dl.util.concurrent.QueuedExecutor$RunLoop.run(QueuedExecutor.java:83) | java.lang.Thread.run(Thread.java:595) | | Thread: Thread-1568 : priority:5, demon:false, threadId:4478, threadState:WAITING, lockName:java.lang.Object@1ffed3a | | java.lang.Object.wait(Native Method) | java.lang.Object.wait(Object.java:474) | EDU.oswego.cs.dl.util.concurrent.LinkedQueue.take(LinkedQueue.java:122) | EDU.oswego.cs.dl.util.concurrent.QueuedExecutor$RunLoop.run(QueuedExecutor.java:83) | java.lang.Thread.run(Thread.java:595) | | Thread: Thread-1569 : priority:5, demon:true, threadId:4479, threadState:WAITING, lockName:java.lang.Object@12f926d | | java.lang.Object.wait(Native Method) | java.lang.Object.wait(Object.java:474) | EDU.oswego.cs.dl.util.concurrent.LinkedQueue.take(LinkedQueue.java:122) | EDU.oswego.cs.dl.util.concurrent.QueuedExecutor$RunLoop.run(QueuedExecutor.java:83) | java.lang.Thread.run(Thread.java:595) | | | | Has anyone seen anything like this before?

[Installation, Configuration & DEPLOYMENT] - Re: Clustering question

by etiennelabuschagne

Well, since no one jumped up and said, idiot, it's so easy to do that, it's either: 1. My question wasn't clear enought 2. No easy answer to it. Or, maybe it's not even a deployment question . . . Any ideas if I'm heading in totally the wrong direction (or am I just impatient. . . ) Any suggestions where else I can ask?

Configure EE application

by Karsten Ohme

Hi, What is the best way to configure an enterprise application? I have here some properties files which should be changeable by the administrator. How can I read the contents of these configuration files, because it is not allowed to use the io package in beans? Is there a better solution for this? Regards, Karsten

[JBoss Portal] - Re: Stylesheets - portal-identity/style.css

by PeterJ

As an alternative, you could just remove the identify portlet from the home page by removing the following from jboss-portal.sar/conf/data/default-object.xml: <window> | <window-name>IdentityUserPortletWindow</window-name> | <instance-ref>IdentityUserPortletInstance</instance-ref> | <region>left</region> | <height>1</height> | </window> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125655#4125655 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4125655

[JBoss Portal] - Re: Stylesheets - portal-identity/style.css

by PeterJ

The clue is in the comment that appears before the injection of the portal-identity/style.css:  Examining portal-identity.sar, in portal-identity.war/WEB-INF/jboss-portlet.xml, you find these lines (twice): <header-content> | <link rel="stylesheet" type="text/css" href="/style.css" media="screen"/> | </header-content> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125653#4125653 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4125653

[JBoss Seam] - Re: s:formattedText problem, it does not handle + char

by norman.richards＠jboss.com

It seems to work for me. Are you sure the "\+" is getting all the way to s:formattedText and that it isn't being turned into a "+" by something else?

[JBoss Seam] - Re: PDF generation : horizontalAlignment does not work

by norman.richards＠jboss.com

Yes, you'll often find that iText works better when your text is organized into paragraphs. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125651#4125651 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4125651

[JBoss Seam] - Re: anyway to generate Seam PDF table in parent/childern for

by norman.richards＠jboss.com

I don't understand what you want from the tables. Maybe you could show an example? All iText components should now support rendered="false". Is it not working for you?

[JBossWS] - Re: reading a local properties file

by gryffin

Well, thank you Peter. Durn if that wasn't wasn't easy once it was explicitly laid out. I'd preferred to keep only classes in the classes directory, but I didn't see any working examples of this so I was stymied. Thanks again, Peter.
