> Looking at how the jbpm_job table is utilized, yes, I think these specific indexes can be removed. Just to clarify. From what I have seen in *our use-case*, under normal circumstances the jbpm_job table has very few entries at any point in time. Seems like entries are added and removed constantly. That being the case, I'm not sure I can see a benefit of spending the extra time/resources maintaining indexes which are never utilized.
I'm going to explore the possibility of removing the job indexes. Can you please https://jira.jboss.org/browse/JBPM create a JIRA issue for this?
> By the way, this is as good a time to explain the use-case that is failing for us. We have a workflow with three steps synchronous steps. The first step takes a couple to a few hundred milliseconds to complete, the second step can take anywhere from 5 to 30 seconds to complete and then the last step usually takes a half a second. When I mentioned jobs earlier, I was referring to workflows contained the three steps just mentioned.
If possible, could you attach your workflow and test harness to the JIRA issue? Please remove any sensitive information you would not like to see published.

Hi,
We are running on JBoss 5.1 / JDK 1.6 on Linux servers. During very high load we are seeing Out of Memory Error and it seems like related to the JBoss remoting.
We took a heap dump and the Memory Analyzer shows the below instance is taking 25% of the memory:
One instance of *"org.jboss.mx.server.MBeanServerImpl"* loaded by *"org.jboss.classloader.spi.base.BaseClassLoader @ 0x415b2fc8"* occupies *65,055,032 (24.64%)* bytes. The memory is accumulated in one instance of *"EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap$Entry[]"* loaded by *"org.jboss.bootstrap.NoAnnotationURLClassLoader @ 0x42f8ba78"*.
The details which is pointing ot the JBoss remoting classes:
Class Name Shallow Heap Retained Heap
1. EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap$Entry[2048] Shallow Heap => 8,208 Retained Heap => 45,693,888

Any thoughts on this please?

We are having issues with a JBOSS Application server running with the following versions
jboss messaging 1.4.6
jboss remoting 2.5.2
primarily being used for messaging purposes.
The server often locks up and the only way to get the clients to connect again is to restart the server.
Looking at the stack trace ,multiple workerthreads are waiting on this following lock

I am trying to find out if its a configuration issue or a code issue on our side ?
Is it possible that one particular client is having problems and that in turn causes the server to lock up ?
Please help.

Hi,
I am facing the same issue as mentioned in the thread. http://community.jboss.org/message/584787#584787 http://community.jboss.org/message/584787
I am using Jboss 5.1.0 with Jboss Messaging.I am receiving the JMS messages from the server for processing in the client(ATG running on Jboss 5.1.0).
If the client is up and running and the server stops in between , i am getting a message as

But if the server restarts again, still the client(which is UP stiill) dosent reconnects, but throws the following Warning.

I downloaded the jboss-remoting.jar 2.2.4( http://www.jboss.org/jbossremoting/downloads.html http://www.jboss.org/jbossremoting/downloads.html) , but still it dosent help me. I saw a JIRA ticket opened on the same( https://issues.jboss.org/browse/JBREM-1144 https://issues.jboss.org/browse/JBREM-1144) and downloaded the jar from there too. Still i m facing this issue.
Kindly let me know on what i m missing with respect to the version or should i have to do any additional configuration to make it working.
Thanks
Sri.

[JBoss Web Services] - CXF client AS7 classloader

--------------------------------------------------------------
Hello, I have an EJB which uses the @WebServiceRef annotation to lookup a webservice client (subclass of Service). I have already read the FAQ, and added "<module name="org.jboss.ws.cxf.jbossws-cxf-client" services="export" />" to the dependencies of the subdeployment containing the EJB in the jboss-deployment-structure.xml. I have tried also services="import" but this makes no difference.
During deployment on JBoss AS 7, configured with standalone-preview.xml, I get the following error:
Failed to start service
