any one tried sending more than 2GIG of data through apache 2.2.3 running mod_proxy to a backend Tomcat box?

My config is :

client --->> Apache/Mod_proxy ---> Tomcat 5.5.x

On the Tomcat side, it's a simple HTTP Servlet that reads the HTTP Input stream and writes to a file.

The results are:

- sending file less than 2 gig is fine
- sending directly to Tomcat is also OK.
- sending file over 2 gig to apache fails. Everything looks normal as far as memory or cpu goes up to the 2GIG mark. Right around the 2GIG mark, Apache stops sending data to Tomcat and start spinning its CPU to 100% and never recovered.

Has anyone encountered the same problem?

Thanks in advance.

from the docs wrote:

Large File Support
httpd is now built with support for files larger than 2GB on modern 32-bit Unix systems. Support for handling >2GB request bodies has also been added.

(since version 2.2.1)

I haven't so large files under windows, yet.

I think that is not implemented under windows Confused
