[jira] [Commented] (ARTEMIS-2113) When AMQP links are opened and closed in quick succession, Artemis doesn’t always respond with attach/detach frames confirming the opening/closing of the links
[ https://issues.apache.org/jira/browse/ARTEMIS-2113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16658436#comment-16658436 ]
Simon Chalmers commented on ARTEMIS-2113:
-----------------------------------------
If we were able to provide a sample test app, which could be run on a Linux environment would that assist in further discussion on this issue?
A simple 64bit Linux enviroment, such as Debian, Ubuntu, Amazon Linux et al, along with the .NET 2.1 SDK would be all that is required to run the sample test app and reproduce the error.

> Key: ARTEMIS-2113
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2113
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: AMQP
> Affects Versions: 2.6.3
> Environment: This test was done in .NET using the Amqp.Net Lite library 2.1.4 (which is the latest version).
> Reporter: Simon Chalmers
> Priority: Major
>
> A trace of a message exchange with Artemis where this has occurred is below. The lines highlighted in yellow show opening and then closing two AMQP links, but Artemis doesn’t respond after that with its own attach/detach frames, which acknowledge the opening/closing of those links. The lines highlighted in green are heartbeat frames sent to Artemis, sent every 15 seconds, which illustrates that one minute passed without receiving the attach/detach frames from Artemis.
