Corey Farrell commented on ASTERISK-24731:
------------------------------------------

So this PJSIP thread issue effected 5 of the 27 backtraces.  I just moved most of {{res_pjsip.c:module_unload}} to {{unload_pjsip}}, it resolved the {{pjsip_endpt_unregister_module}} crash.  Unfortunately 4 of the 5 went on to crash at {{pjsip_endpt_destroy(ast_pjsip_endpoint)}}.

> res_pjsip_session cannot be unloaded or shutdown, causing huge numbers of leaks to be reported by REF_DEBUG or valgrind. This makes it impossible to do automated checks for memory leaks against chan_pjsip.  All testsuite tests to fail if REF_DEBUG is enabled and res_pjsip_session is loaded.
> This is follow up to ASTERISK-24485.  As with that bug it's important for the module to clean itself up on graceful shutdown, less important to allow users to unload the module without shutdown.
