<p>The issue is in the tm module. While processing the resumed reply, since we are in a case of final reply for the transaction, we delete it after sending it out. This is causing the carsh when, at the end of t_continue we try to access the branch's reply.<br>
I've open a PR <a href="https://github.com/kamailio/kamailio/pull/1063" class="issue-link js-issue-link" data-url="https://github.com/kamailio/kamailio/issues/1063" data-id="220332076" data-error-text="Failed to load issue title" data-permission-text="Issue title is private">#1063</a> with a fix.<br>
Also, why do you need to suspend the reply in this case? Wouldn't be fine to not suspend the transaction?<br>
See $http_req(suspend) <a href="http://www.kamailio.org/docs/modules/devel/modules/http_async_client.html#idp21739572">http://www.kamailio.org/docs/modules/devel/modules/http_async_client.html#idp21739572</a>.</p>
