JMS (MQ) deconnexion when using job with tFTPConnection

[Anonymous]

Hello,

I have currently realize a route where I get a message from WMQ, push the file locally to send it through SFTP (with a Proxy) to a distant server. To send the file through the proxy, I need to call a job and use the components tFTP<X> (Connection, Put, Rename...).

Individually all the flow is working well.

When I launch my route, I get the first message and the message is sent successfully to the distant server, I even got the last log message from my route. Nevertheless, after this message I got the following message (in talend_global.log)

2019-10-02T15:53:47,519 | ERROR | Camel (shop.elt01put_parts_0_1.Elt01_PUT_PARTS) thread #15 - JmsConsumer[MQ.APP.PART.SHOP.IN] | .DefaultMessageListenerContainer 947 | 228 - org.apache.servicemix.bundles.spring-jms - 4.3.14.RELEASE_1 | Could not refresh JMS Connection for destination 'MQ.APP.PART.SHOP.IN' - retrying using FixedBackOff{interval=5000, currentAttempts=581, maxAttempts=unlimited}. Cause: JMSWMQ0018: Failed to connect to queue manager 'FRMQ1' with connection mode 'Client' and host name 'frmq1.it.internal.net(1416)'.; nested exception is com.ibm.mq.MQException: JMSCMQ0001: WebSphere MQ call failed with compcode '2' ('MQCC_FAILED') reason '2538' ('MQRC_HOST_NOT_AVAILABLE').

The JMS connexion is not able anymore to connect to the queue WMQ.

The worse, if I use the route through Karaf, is that all the JMS connexions generate the same errors, if my route treats one message (the messages appear directly after the first treatment).

I have done some tests, if I remove the tftpConnection (and all the tftp components) and do an action (remove the input file for example), I do not got any error message.

I join a screenshot of the route and a screenshot of the job (please note that I have deactivate/reactivate the component to perform my test).

Thank for your help

Hello,

Can you please clarify in which Talend version/edition you are?

Best regards

Hello,

I am using Talend Studio 7.1.1

Additional test that we have performed:

• Removing the SFTP components in the job and we do not have anymore the error.
• Adding sleep time in the job and before the last log of the route confirms that the JMS connection failed only at the end of the route.
• Through studio dividing the route with JMS to MQ connection and the job with SFTP connection and running both of them in the studio (the same) does not trigger the error. But, doing the same through karaf and all the JMS connection (MQ connection only for this component) present in karaf goes with the JMS connection issue.
• Executing the Job without a route solves the issue but it is not what we would like to perform.

Any help will be welcome to this specific case
