thin eats all memory when requesting a large static file
Reported by rolando | 2008-09-01 22:23:33 UTC | in Future
If requesting a large (over 600MB) static file, thin eats a lot of memory, here are some hints:

hey Rolando,
This all depends on how you send the file in the code. Are you using Rails? Can you paste the code that sends the file.
Also tell me which version of Thin you are using (thin -v).
Thx for reporting!

Or if you really want to do it in Ruby you should use streaming.
