We have a new Alert email notification process (EOEN_ALERT) enabled that uses the Service operation EOEN_MSG to publish email message to the email server. We are having issues with the email messages being published 5 times (4 duplications sent 20 minutes apart from each other) so we looked further at the Integration Broker queue EOEN_MSG_CHNL and noticed that the very last (newest) transaction will stay in a 'Working' status for 20 minutes, and then issue a Retry before it finishes processing. When this occurs the messages that already had been processed on the prior attempt are published again (hence the email duplication). It keeps performing retries until the Retry count reaches 6, and then the status goes to Timeout and the emails stop.
Is there a way we can adjust (increase) any parameters for when the timeout occurs? Thank you.
