--------------------------------------------

Hi, when I look into backtrace.txt, I see

1.)
Thread 1 (Thread 0xb76a1b90 (LWP 27324)):
#0  0x08089bb0 in __ao2_find ()  <--- SEGFAULT
#2  0x08161165 in ast_add_extension2_lockopt ()
#3  0x003d9a33 in pbx_load_config () at pbx_config.c:1644
#4  pbx_load_module () at pbx_config.c:1848
#5  0x0812155a in ast_module_reload ()
#6  0x080cdff9 in handle_reload ()
#7  0x080c9a69 in ast_cli_command_full () <--- Reload called from CLI
#

2.)
Thread 40 (Thread 0xb7f786d0 (LWP 31340)):
...
#4  0x0807ea1a in quit_handler ()         <--- TERM Signal received
#5  0x080844dc in main ()
...


So I personaly think, that someone stopped the asterisk per SIGNAL (like SIGTERM or so) while executing a reload.
