> endpoint=realtime,ps_endpoints
> endpoint/cache=memory_cache,maximum_objects=3000,expire_on_reload=yes,object_lifetime_maximum=30
> aor=realtime,ps_aors
> aor/cache=memory_cache,maximum_objects=3000,expire_on_reload=yes,object_lifetime_maximum=30
> The endpoint with aor's static contact and qualify_frequency = 30
> I think one thread 'sorcery_memory_cache' clears cache due to expiry
> and another thread 'pjsip_options' uses the same cache object which is already freed.
