hi,all

This is the url,
http://124.115.14.23/http_imgload.cgi?/rurl4_b=86e76ed3fe8a925d6727a22b2df8fa6dd25a6ea7fb934efe3d7336ce51a4a93f3ae2dea54fb40d43a4d68660f07135d4f62b761d36493b0aef204c08c35da510918f6ec079d49b4ab9a559a639335ffca7a41363&a=36&b=31&sid=8yw8WRb6JHK1CQ
when I visit it via the nginx proxy, the IE is always waiting for about
the keepalive timeout, then render the image but not full, the image size is
about 32K.
when I visit the image by a browser directly there is no problem, the
image size is about 35K.
So I turn on the nginx debug, the error seems ok, at the end there is a
upstream read timeout.
I did a tcpdump, the nginx box got all the response content, but the
upstream(124.115.14.23) did not close the connection. After about 3
seconds,( I set keepalive timeout 3), nginx box sent a FIN packet to the
upstream, then receive a FIN.

nginx is 0.7.24. kernel is 2.6.16.
so what can I do? upgrade the kernel?
