Corey Farrell commented on ASTERISK-28155:
------------------------------------------

I don't have time to prepare a patch right now but I suspect adding ast_module_ref to load_module inside {{if (!ast_sip_get_mwi_disable_initial_unsolicited()) {}}, add ast_module_unref to the end of send_initial_notify_all should prevent the shutdown race.

> As shown with the attached backtrace it is possible for a crash to occur at shutdown due to a container going bye bye when it is then being used. We should do an audit for other cases of this too.
