I want to experiment with using the async module. I added the module and updated my request_route to call async_task_route() and put all the existing routing logic in a new route. Unfortunately my kamailio is crashing looking up a cfg_get variable. The exact same route logic works fine in the normal child process, its only when its run in a async_worker that it fails. Is this a known issue? I can see in the core file that there is no group handle in the cfg_group_t (its 0x0), but I know nothing about how that gets set and where. Thanks in advance for any help Malcolm
