Alfresco community 7.4.X e 23.X
I have an installation at a customer's site with very slow write disks where it seems that activemq times out and alfresco cannot refresh the connection, which always returns nothing.
Here the error
ERROR [component.jms.DefaultJmsMessageListenerContainer] [Camel (alfrescoCamelContext) thread #2 - JmsConsumer[acs-repo-transform-request]] Could not refresh JMS Connection fo
r destination 'acs-repo-transform-request' - retrying using FixedBackOff{interval=5000, currentAttempts=2761, maxAttempts=unlimited}. Cause: Error while attempting to add new Connection to the pool; nes
ted exception is java.lang.NullPointerException: Cannot invoke "org.apache.activemq.jms.pool.ConnectionPool.incrementReferenceCount()" because "connection" is null
and i'm forced to restart alfresco to solve the error .
After analyzing the issue to try to resolve the problem in the “messaging-context.xml” context file in the “alfresco/subsystems/Messaging/default” directory, I could try to resolve it by bypassing the Polled Factory, reducing performance but ensuring direct access to activemq with the following configuration in the alfresco extensions folder
<alias name="activeMqConnectionFactory" alias="pooledConnectionFactory"/>
Override: Disables the JMS pool. This causes Alfresco to use the direct ActiveMQConnectionFactory connection
instead of the pooledConnectionFactory bean. This creates a true Spring alias: whenever Alfresco requests pooledConnectionFactory, it will receive the activeMqConnectionFactory bean.
What do you think? Could this make sense? My tests seem to show improvement.
