When someone clicks on the link to download it, lighttpd ends up actually caching the whole file to the ram on the server and usually brings the server into swap and then eventually crashes I need a fix for this because this is a huge problem and all i need is 4 people downloading a 300-500 meg file and my server is completely gone.
