Hi,

Listen backlog in Nginx defaults to NGX_LISTEN_BACKLOG=511 on Linux & other platforms (excepting FreeBSD & MacOS), not to system somaxconn (why does it differ for different OSes?).

It’s not a problem to increase it using «backlog» option of «listen» directive for HTTP servers (http://nginx.org/en/docs/http/ngx_http_core_module.html#listen),
but there is no such option for stream server (http://nginx.org/en/docs/stream/ngx_stream_core_module.html#listen).

Is there any proper way to increase listen queue length for stream server (without patching source code) or globally? Seems to be a subject to fix.
