-------------------------------------------------------------------

attached file originate_bridge_channel_count_test.txt is the actual console output with added warning logs that give me the channel count every time a endpoint_snapshot gets created.

*dialplan was as simple as:*
{code:title=extensions.conf}
[test]
exten => h,1,Hangup()

exten => originate,1,set(GLOBAL(channelorig)=${CHANNEL})
exten => originate,2,wait(20)

exten => bridge,1,Bridge(${channelorig})
{code}

*cli commands to make a call.*
{code:title=cli commands}
originate SIP/201 extension originate at test
originate SIP/201 extension bridge at test
{code}

endpoint *SIP/201* is another asterisk running on another machine and just receiving the call and putting the call to wait application.

> 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.
