[asterisk-bugs] [JIRA] (ASTERISK-28197) stasis: ast_endpoint struct holds the channel_ids of channels past destruction in certain cases

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28197?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=245754#comment-245754 ] 

Mohit Dhiman commented on ASTERISK-28197:
-----------------------------------------

I tried to stop the removal of subscribers from the non-pbx channel by adding a flag in ast_channel which stoped the channel_ids count from increasing forever but now the subscribers are not getting removed from the channel.

> For every call i made through asterisk to an endpoint the {{ast_endpoint}} struct adds that channel to its channel_ids {{ao2_container}} and after the channel gets destroyed it should remove it from that channel_ids list but the {{channel_count}} for endpoint is continuously increasing for every call i make to that endpoint.
> i verified this by adding some warning logs to the {{ast_endpoint_snapshot_create}} function of {{main/endpoints.c}}, this log prints the channel_count for that endpoint.
> [Dec 5 17:14:45] WARNING[7397] endpoints.c: channel count: 107069 max channel: -1
> [Dec 5 17:14:45] WARNING[7397] endpoints.c: channel count: 107070 max channel: -1
> [Dec 5 17:14:45] WARNING[7397] endpoints.c: channel count: 107071 max channel: -1
> [Dec 5 17:14:45] WARNING[7397] endpoints.c: channel count: 107072 max channel: -1
> here channel count corresponds to
> {{channel_count = ao2_container_count(endpoint->channel_ids);}}
> also there are no more than 400 channels at any instance.
