[jira] [Comment Edited] (DISPATCH-583) Random segmentation fault
[ https://issues.apache.org/jira/browse/DISPATCH-583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15712175#comment-15712175 ]

Ok ... I'm quite sure that the segmentation fault is related to connection suddenly closed. I have a systematic way for crashing, using my mqtt-frontend project and running this specific test :
mvn -Dtest=PublishTest#publishQoS0toMqtt test
I have to fix synchronization in my unit test to avoid this suddenly connection close but now we have more info to discover why the router crash.

> Hello,
> working with the following project :
> https://github.com/EnMasseProject/mqtt-frontend
> using the router, I have random "segmentation fault" errors when the SubscribeTest is executed. It happens running the test 3-4 times ... or 20 times ... totally random.
> You can reproduce it, cloning the above repo and running :
> mvn -Dtest=SubscribeTest test
> I used the route built from the repo source code (about 2 weeks ago) but applying the patch for message annotations on that.
> I got the backtrace of one of the crash :
