the org.jencks.JCAConnector is configured as follows:
<bean id="inboundConnectorStage1" class="org.jencks.JCAConnector"
lazy-init="true">
<property name="jcaContainer" ref="jencksJCAContainer1"/>
<property name="activationSpec">
<bean class="org.apache.activemq.ra.ActiveMQActivationSpec">
<property name="destination" value="stage1Queue"/>
<property name="destinationType" value="javax.jms.Queue"/>
<property name="acknowledgeMode" value="Dups-ok-acknowledge"/>
<property name="maxSessions" value="${stage1.maxSessions}"/>
<property name="maxMessagesPerSessions"
value="${stage1.maxSessions}"/>
</bean>
</property>
<property name="ref" value="stage1"/>
</bean>
where initially stage1.maxSessions=250 and the threadpool size was set to 300.
I have been able to avoid this problem reducing the concurrency, but of course
this
is not the solution.
