mod_net_proxy: Use safer util.format for generating description string (thanks tom) It appears that server_event may emit port numbers (src_port() in this case) as strings, rather than integers. This causes string.format() to throw an error. Prosody's util.format is a more forgiving formatter and won't throw an error. The server_event behaviour may be best fixed for the sake of consistency, though.

module:depends("smacks");

module:hook("smacks-ack-delayed", function (event)
	if event.origin.type == "s2sin" or event.origin.type == "s2sout" then
		event.origin:close("connection-timeout");
		return true;
	end
end);
