…ode (#59769) The crash occurred because evhttp was created as a local shared_ptr in the lambda function, and its destruction happened after event_base_dispatch returned. This caused use-after-free issues when ASAN/UBSAN tried to verify the object dynamic type during shared_ptr destruction. Fix by: 1. Moving evhttp objects to class member _evhttp_servers for explicit lifecycle management 2. Reordering resource cleanup in stop(): - Close server_fd first to reject new connections - Break event loops to make dispatch return - Wait for worker threads to finish - Clear evhttp before event_base (correct dependency order)
