<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is not safe. When you find a member and grab a reference to it, you hold that reference until the member is no longer being used by that thread. This function finds the member, unrefs it, and then returns a pointer to the unrefed memory.
Also, it looks like the queue should be unrefed after unlocking it after finding it by load_realtime_queue().</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">app_queue logs the events ADDMEMBER and REMOVEMEMBER with the agent field set to the interface value rather than the membername value when a member is added with a state_interface value set. However all other member related queue events are logged with the membername when a state_interface is set. It would seem that these ADD/REMOVE MEMBER events should log the agent field in the same manner.
This patch addresses the original issue reported in https://issues.asterisk.org/jira/browse/ASTERISK-14769 by providing a queues.conf general configuration option log_membername_as-agent. Setting log_membername_as_agent = yes will cause the membername to be logged in the agent field for ADDMEMBER and REMOVEMEMBER queue events if a state_interface has been set.
The default value (log_membername_as_agent = no) does not alter the existing logging for the ADDMEMBER and REMOVEMEMBER events to maintain existing (buggy) behavior for the sake of backwards compatibility. </pre>
