Problems with esb module with many services

[hauch]

I run into the following exception when I try to invoke a service in an esb module with >20 services.

12:46:05,888 WARN [ServiceController] Problem starting service jboss.esb:deployment=large_service-0.33.06-SNAPSHOT.esb

I have reproduced the error in a setup with 25 identical services on the form

 <service category="Smile" name="Service1" description="beskrivelse">
 <listeners>
 <jms-listener name="JMS-Channel" is-gateway="false" busidref="Service1Channel" maxThreads="1"/>
 <jms-listener name="JMS-Channel" is-gateway="true" busidref="Service1GW" maxThreads="1"/>
 </listeners>
 <actions>
 <action name="action_Service1" class="org.jboss.soa.esb.actions.SystemPrintln">
 <property name="printfull" value="true"/>
 <property name="message" value="****** SERVICE Service1} ***********"/>
 </action>
 </actions>
 </service>

These are invoked via a file gateway.

The error occurs when I have >20 of these, but everything work fine if I have less.
I have reproduced the error on a jbossesb-server-4.4.GA with no modifications.

Is this a bug or a configuration issue?

[kconner]

It is a configuration issue. By default the pool is limited to 20.

You need to increase the pool or split up your esb artifact into smaller artifacts.

Excellent. Thanks for the reply.
Where do I configure the pool?

[hauch]

I'm sorry but it is not clear to me, which pool we are talking about - and hence how to configure it?

[scottdawson]

The org.jboss.soa.esb.jms.connectionPool property in jbossesb.sar/jbossesb-properties.xml

Yes, that did it.
Thanks a lot!
