Environment Details:

OS: Redhat Linux

JBoss AS: 4.2.3

JDK:1.6.0_13

We are getting following error on our production server.

[ServiceInvoker] Unresponsive EPR: JMSEpr [ PortReference < <wsa:Address jms://jbesb2.ion.open.com:1099/queue/sendNotification_ejbprocessor_request_esb/>, <wsa:ReferenceProperties jbossesb:java.naming.factory.initial : org.jnp.interfaces.NamingContextFactory/>, <wsa:ReferenceProperties jbossesb:java.naming.provider.url : jbesb2.ion.open.com:1099/>, <wsa:ReferenceProperties jbossesb:java.naming.factory.url.pkgs : org.jnp.interfaces/>, <wsa:ReferenceProperties jbossesb:destination-type : queue/>, <wsa:ReferenceProperties jbossesb:specification-version : 1.1/>, <wsa:ReferenceProperties jbossesb:connection-factory : ConnectionFactory/>, <wsa:ReferenceProperties jbossesb:persistent : true/>, <wsa:ReferenceProperties jbossesb:acknowledge-mode : AUTO_ACKNOWLEDGE/>, <wsa:ReferenceProperties jbossesb:transacted : false/>, <wsa:ReferenceProperties jbossesb:type : urn:jboss/esb/epr/type/jms/> > ] for message: header: [  ]

This error appears and no transactions are processed. I know little bit of that either the service takes to long time or it lost the service reference. But we were fine before and now after 12 hrs of running we are getting this issue.

Please help me. let me know if you need more details.

I'm not sure but you might want to look into the available amount of threads to your ESB. If they are all occupied you can get an unresponsive EPR.

currently 700 threads are live and where can I find max threads?

[tcunning]

In jbossesb-properties.xml :

<property name="org.jboss.soa.esb.jms.connectionPool" value="20"/>

[rajasundaram]

it is set to 150 on our production server

        <property name="org.jboss.soa.esb.jms.connectionPool" value="150"/>

but the cpu usage is not high.

[h.wolffenbuttel]

Did you try to increase the value?

[rajasundaram]

Currently there was no load on the server but one of our call I mention on my original post was failing. We restarted the server early morning.

Can I use jmx-console to increase the pool size. If so please tell me.

[tcunning]

No, it is not editable in jmx-console - you need to edit into your jbossesb-properties.xml in jbossesb.sar.

[rajasundaram]

How to use jmx-console to see the current jms connection pool count and other details.

[tcunning]

Again, not available in jmx-console.       The ESB Property Service exposes the location of the properties file but not its values.      If you want to verify this property, you could use a debugger, or write some code which logs it.

In juddi db publisher table maximum services per business is set to 25 but on the services table has 147 records. Do we need to set 150 or more on publisher table?

[rajasundaram]

jbossesb-properties.xml under 'connection' properties property name 'max-pool=size' it looks like a typo. any impact for this typo and what is connection properties?
