I now think that the confusion comes from what "the default value" for proxy_busy_buffers_size is. The documentation has one set of words, which is correct once you know how it is intended to be interpreted. If we can find a set of words that is both correct and clear, we can probably get the documentation changed to help the next person. I think that the key is: if not explicitly defined, the value for proxy_busy_buffers_size is "the bigger of: twice proxy_buffer_size; and the size of two proxy_buffers". By default-default, that is the 8k or 16k that the documentation summary shows. But when you set a big proxy_buffer_size value, you are implicitly increasing proxy_busy_buffers_size as well. And then the other requirement kicks in -- proxy_busy_buffers_size must be not bigger than "proxy_buffers number-minus-one times size". Also, if you want to explicitly set proxy_busy_buffers_size, you cannot make it be smaller than a single proxy_buffers, or than proxy_buffer_size. So with all default values on a 4k page system, proxy_buffers is "8 4k" (32k total, and 28k is the maximum for proxy_busy_buffers_size); proxy_buffer_size is 4k; and proxy_busy_buffers_size is 8k. If you want to set proxy_buffer_size to more than 14k, you must either also increase proxy_buffers (in number or size); or explicitly set proxy_busy_buffers_size to 28k or lower (while not being smaller than proxy_buffer_size). Hopefully this does not make things more confusing...
