Please note: length of a document curl tries to PUT is just 64982.

Just a side note: "HTTP/1.1 201 Created" line is missed here.
It's likely a problem of verbose output in the old version of curl
you are using. Recent versions of curl correctly show it like this:

< HTTP/1.1 100 Continue
} [data not shown]
< HTTP/1.1 201 Created
< Server: nginx/1.5.4
....

.... and the file created is exactly as PUT by curl. That is,
there is no problem in nginx.

Using "curl --data-binary @..." instead of "curl -d ..." should
help.
