[SR-Users] app_python module fails with "AttributeError: init_modules() has failed"

Good morning, I'm trying to use the app_python module with Kamailio but i'm unable to even reach a point where it loads my python module. My host: CentOS release 6.3 (Final) 2.6.32-042stab076.7 x86_64 The installed packages: [root@host ~]# rpm -qa | grep kamai kamailio-4.0.1-1.1.x86_64 kamailio-mysql-4.0.1-1.1.x86_64 kamailio-python-4.0.1-1.1.x86_64 Configuration modification: #!define WITH_MYSQL loadmodule "app_python.so" The python module: [root@phone ~]# cat /usr/local/etc/sip-router/handler.py class Handler(object): def child_init(self, y): return 0 def mod_init(): return Handler() When I start Kamailio, it fails like this: [root@host ~]# kamailio -D 1 -E -e loading modules under /usr/local/lib/kamailio/modules_k/:/usr/lib64/kamailio/modules/ 0(729) NOTICE: <core> [sr_module.c:627]: /usr/lib64/kamailio/modules/app_python.so: exports dlflags interface is deprecated and it will not be supported in newer versions; consider using mod_register() instead Listening on udp: 127.0.0.1:5060 udp: 10.3.105.49:5060 tcp: 127.0.0.1:5060 tcp: 10.3.105.49:5060 Aliases: tcp: phone:5060 tcp: phone.dev.net2.irg:5060 tcp: localhost4:5060 tcp: localhost4.localdomain4:5060 tcp: localhost:5060 tcp: localhost.localdomain:5060 udp: phone:5060 udp: phone.dev.net2.irg:5060 udp: localhost4:5060 udp: localhost4.localdomain4:5060 udp: localhost:5060 udp: localhost.localdomain:5060 WARNING: no fork mode and more than one listen address found (will use only the first one) 0(729) INFO: <core> [tcp_main.c:4846]: init_tcp: using epoll_lt as the io watch method (auto detected) 0(729) INFO: rr [../outbound/api.h:49]: Failed to import bind_ob 0(729) INFO: rr [rr_mod.c:159]: outbound module not available 0(729) INFO: usrloc [hslot.c:53]: locks array size 512 0(729) ERROR: <core> [sr_module.c:939]: init_mod(): Error while initializing module db_mysql (/usr/lib64/kamailio/modules/db_mysql.so) 0(729) ERROR: app_python [python_support.c:132]: mod_init: Unhandled exception in the Python code: AttributeError: init_modules() has failed 0(729) ERROR: <core> [sr_module.c:939]: init_mod(): Error while initializing module app_python (/usr/lib64/kamailio/modules/app_python.so) ERROR: error while initializing modules And with -d -d -d : *snip* 0(751) DEBUG: <core> [sr_module.c:674]: find_export_record: found <t_release> in module tm [/usr/lib64/kamailio/modules/tm.so] 0(751) DEBUG: <core> [sr_module.c:935]: DEBUG: init_mod: app_python 0(751) DEBUG: <core> [sr_module.c:935]: DEBUG: init_mod: db_mysql 0(751) ERROR: <core> [sr_module.c:939]: init_mod(): Error while initializing module db_mysql (/usr/lib64/kamailio/modules/db_mysql.so) 0(751) ERROR: app_python [python_support.c:132]: mod_init: Unhandled exception in the Python code: AttributeError: init_modules() has failed 0(751) ERROR: <core> [sr_module.c:939]: init_mod(): Error while initializing module app_python (/usr/lib64/kamailio/modules/app_python.so) ERROR: error while initializing modules 0(751) DEBUG: tm [t_funcs.c:118]: DEBUG: tm_shutdown : start 0(751) DEBUG: tm [t_funcs.c:121]: DEBUG: tm_shutdown : emptying hash table 0(751) DEBUG: tm [t_funcs.c:123]: DEBUG: tm_shutdown : removing semaphores 0(751) DEBUG: tm [t_funcs.c:125]: DEBUG: tm_shutdown : destroying tmcb lists 0(751) DEBUG: tm [t_funcs.c:128]: DEBUG: tm_shutdown : done 0(751) DEBUG: <core> [mem/shm_mem.c:242]: shm_mem_destroy 0(751) DEBUG: <core> [mem/shm_mem.c:245]: destroying the shared memory lock I've been trying all the configuration permutation I could think off. Am I missing a package or something in the configuration ? Regards, -- Phil.
