Hi Praveen, You’d probably have to check the exact reason why epoll_ctl fails. But some quick comments: - we’re moving away from binary api in vcl. We’re still building it but it’s slowly being deprecated. I’d recommend switching to sapi api. - maybe check vl_api_app_attach_reply_t_handler and confirm that wrk->app_event_queue fd we got from vl_socket_client_recv_fd_msg2 is reasonable.
