Receiver JMS channel in error state

[ashish_goel4]

Hi Experts,

Currently we are facing a problem with few JMS receiver channels. We are using sending messages to TIBCO EMS queues.

Error message :

Message processing failed.Unable to write new JMS message body for message:  * : ConnectorException: Connector for ConnectionProfile of channel: * node: * having object id: * was unable to create a new javax.jms.TextMessage message: java.lang.NullPointerException

Can anyone tell why this happened. After restarting the channel and re-sending the "system error" messages again from PI resolved it.

But this should not happen as they were running successfully earlier.

Thanks,

Ashish

Hi Ashish,

When you get the error, can you ask the JMS team to check if they are getting calls from PI or not. I think it might be a JMS driver issue but you need to involve JMS team and decouple the issue (if it is PI or JMS).

Hi Ambrish,

It was working fine earlier. And after re-starting the channel issue is resolved.

But, I just wanted to know the root cause of this.

Thanks,

For quick solution, restart the adapter and see the error goes away.

it looks for some time connectivity broken or channel moved to locked status. (my guess)

Hi Raja,

My observation is also same that this happened due to connection break.

But then channels should re-establish connection automatically , why channel re-start was required.

Thanks,
