Hi, I've an issue with send-proxy on HAProxy-1.5-dev19 running on FreeBSD. Since dev13 I can't get send-proxy to work on FreeBSD, connections to the backend server (another haproxy with accept-proxy bind option) are imediately closed.
Version dev12 works correctly on FreeBSD, and dev19 on Linux works too.
Connection seem to be closed in stream_interface.c (out_error) :
470 if (ret < 0) {
471 if (errno == EAGAIN)
472 goto out_wait;
473 goto out_error; <<<<<<
474 }
