<p style="white-space: pre-wrap; word-wrap: break-word;">Sorry I don't have time to do a complete review but I think you need to add `ast_module_shutdown_ref` at the end of load_module right before it returns success. This bug shows that something has callbacks into res_pjsip_mwi without holding a module reference so CLI `module unload res_pjsip_mwi` could cause a crash.</p><p><a href="https://gerrit.asterisk.org/c/asterisk/+/12998">View Change</a></p><ul style="list-style: none; padding: 0;"></ul><p>To view, visit <a href="https://gerrit.asterisk.org/c/asterisk/+/12998">change 12998</a>.
