[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=228824#comment-228824 ] 

Joshua Colp commented on ASTERISK-25137:
----------------------------------------

This is continuing to occur to some degree on 13 causing the tests/endpoints/statsd and tests/rest_api/applications/subscribe-endpoint/nominal/tech tests to fail despite the changes that have been done. However it is not occuring on master. Quite odd.

> If I subscribe topic ast_endpoint_topic_all_cached I receive all endpoint messages twice.
> In function endpoint_internal_create called from ast_endpoint_create single endpoint topic is created and forwarded to  ast_endpoint_all topic by calling
>  
> stasis_cp_single_create(ast_endpoint_cache_all(), endpoint->id);
> After that, same single topic is forwarded to tech_topic which is also forwarded to ast_endpoint_all topic. 
> Example of resulted topic tree is
> SIP/8888 -> SIP -> ast_endpoint_all
> SIP/8888 -----------------^
> and subscriber who subscribes ast_endpoint_all or higher level topic receives endponit messages twice.
> I think direct forwarding from single topic to ast_endpoint_all can be deleted from the tree (not created at all) and I can prepare patch if somebody confirms that it is correct way how to fix the problem
