[Messaging, JMS & JBossMQ] - MDBS threads are in TIMED_WAITING state
by assaf49
Hi,
We are running on JBoss 4.0.5, jdk 5.
We are performing load test, and sending ~20000 JMS messages per minute.
We notice the the Jms queue depth is continuously growing (it reaches about 300000 !).
We increased the number of MDBs consuming messages from this queue to 200, but for some reason it seems most of the MDBs (175 out of 200) are in state : TIMED_WAITING . (see example for one of the MDBs in the thread dump below)
"JMS SessionPool Worker-198" daemon prio=10 tid=0x00f11800 nid=0x184 in Object.wait() [0x1327f000..0x1327fa70]
java.lang.Thread.State: TIMED_WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
at EDU.oswego.cs.dl.util.concurrent.SynchronousChannel.poll(SynchronousChannel.java:353)
- locked <0xaeaa5788> (a EDU.oswego.cs.dl.util.concurrent.LinkedNode)
at EDU.oswego.cs.dl.util.concurrent.PooledExecutor.getTask(PooledExecutor.java:723)
at org.jboss.jms.asf.StdServerSessionPool$MyPooledExecutor.getTask(StdServerSessionPool.java:397)
at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:747)
at java.lang.Thread.run(Thread.java:619)
Our application is running on a very strong T2000 machine with 32 cpu ( cpu load is 15%) and 3 giga memory ( memory consumption is 50%).
Our question: why are most of our Jms threads (MDBs) in TIMED_WAITING state instead of consuming messages from the queue?
your help is appreciated
John

[JBoss Seam] - Re: User Navigation Design Pattern
by Delphi's Ghost
I started to have another look at the Issues example application that comes with Seam since it has a lot of nested conversations as you drill down from project to issue etc.. kind of similar to what I'm looking for.
Looks like it has problems also. If you change the project name, click done (no update) it refreshes the project and reverts back to its original name. However, if you change the project name, and then edit an issue, and save the issue, when you go back to the project page and click done, it does not roll back the change even though you never saved the project change.
The same also applies if you repeat the process with the Issue and a comment. You can't save the comment without forcing updates to the Issue.
However, it does not use the manual flushmode, so that would explain why the objects are updated when they shouldn't be, so I guess this is just a bug in the issues application. It would be interesting to see how the Issues app would get around the problem of drilling down without forcing everything in the parent conversations to be saved.
