[jira] [Comment Edited] (QPIDJMS-409) JMS Scheduled Delivery
delivers messages before time under load
[ https://issues.apache.org/jira/browse/QPIDJMS-409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16581856#comment-16581856 ]

---------------------------------------------------------------
I can't easily give a sample - especially as it comes under load.
I've enabled debugging as requested. I've had a look in the log and really couldn't see anything much. Maybe I'm missing something.
I've attached a log of a "successful" message send with a delayed delivery message being sent. Can you see anything there which shows that the delivery was being delayed? If not, I'm not sure where else to go with this.
If you can see the correct parameters which show a delayed delivery, what I'll do is then find a case where it fails and attach that too. If you could point out where in the trace it is, so I can look for it myself and maybe get a clue as to what is happening.

> Key: QPIDJMS-409
> URL: https://issues.apache.org/jira/browse/QPIDJMS-409
> Project: Qpid JMS
> Issue Type: Bug
> Components: qpid-jms-client
> Affects Versions: 0.35.0
> Environment: Application is a Spring Boot application - version 2.0.4.RELEASE
> Qpid JMS Client version is 0.35.0
> Operating system where problem occurs is Windows 10
> I have found this problem using the following different message brokers:
> * Apache Artemis 2.4.0
> * Apache Artemis 2.6.2
> * Apache Qpid Broker 7.0.6
> Reporter: Ian Rowlands
> Priority: Major
> Attachments: successful_delayed_delivery.txt
>
>
> When under system load, the Qpid JMS client doesn't handle scheduled message delivery correct - it delivers the message prior to the required time.
> When running one request, the scheduling works correctly. The load to reproduce this isn't very high (i.e running about 5 of my job processes simultaneously seems to trip it up pretty quickly).
> I have used different JMS Brokers with the same client code and the same problem occurs with both Brokers (see environment).
> I am using Spring JMS Template to send the JMS message. The key piece of code is something like:
> {{delayedDeliveryjmsTemplate.setDeliveryDelay(timeoutPeriod);}}
> {{delayedDeliveryjmsTemplate.convertAndSend(queueName, timeoutMsg, (Message jmsMessage) -> {}}
> {{ jmsMessage.setStringProperty(OBJECT_TYPE_FIELD, timeoutMsg.getClass().getSimpleName());}}
> {{jmsMessage.setStringProperty(OBJECT_TYPE_FIELD, timeoutMsg.getClass().getSimpleName());}}
> {{ return jmsMessage;}}
> {{});}}
> I realise you want more logging details but I'm unsure what would be best to log. Please let me know and I'll do so.
