Truncated output for css with nginx 1.2

[forforums]

This is on centos and nginx 1.2.

I have a jetty server in the back and it is https all the way thru.
Intermittently the browser hangs trying to read a css that the app is
using. This file is about 30076 bytes and interestingly it always hangs
at 16104 bytes. Now when I chomp the file down to 6k I have not been
able to reproduce this problem!!

Jetty server returns a 200OK and 30076 bytes, but the logs in nginx
shows 

10.23.8.163 - - [15/May/2012:21:53:48 +0000] "GET /app/application.css
HTTP/1.1" 200 16104 "https://loginlab.com/somesite" "Mozilla/5.0
(Ubuntu; X11; Linux x86_64; rv:8.0) Gecko/20100101 Firefox/8.0" "-"
"RC4-SHA" "-" 0.062 0.062 - OK

when this happens. So I build nginx with debug and turned on debug for
the hosts involved and I get this for the case when the file is chopped

Seems like read gets a SSL_ERROR_SYSCALL. Any pointers to what else I
can look at to get to the bottom of this problem is much appreciated.

Thanks
