499 Code - The connection resets after 1 minute

[krukmat]

I have a django view which lasts more than a minute. 
But after the first minute, the browser shows me the connection is
reset. 
If I read the access log, I find this:
 "GET
/2.1/jmsf/events?apikey=6ff9131a-2c37-4584-9988-7e0e4da91577&m=2010-06-18+00%3A33%3A34.None.None
HTTP/1.1" 499 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_7)
AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.202 Safari/535.1"

I tried adjusting client_header_timeout,
client_body_timeout,keepalive_timeout,fastcgi_read_timeout
,fastcgi_connect_timeout,fastcgi_send_timeout and send_timeout. But It
didn't work.
Thanks
