Corey Farrell commented on ASTERISK-24683:
------------------------------------------

I just looked over your backtraces.  One thread shows logger_close() is currently running.  This means that pbx_shutdown() has already completed, contexts_table has already been destroyed.  Setting {{contexts_table = NULL}} after it is destroyed would likely help, but not eliminate the risk of crash during a restart or stop 'now'.
