           Summary: Server has a memory leak when handling chunked
                    responses.
           Product: Apache httpd-2
           Version: 2.2.3
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: inders@integral.com


We are running Apache Server 2.2.3 as a reverse proxy for our application 
servers.

Our application returns responses with Transfer-Encoding: chunked, and we 
observer tha the apache server hangs due to high memory utilization after a 
short while.

On doing further analysis of the packets flowing between the apache server and 
the client (IE6), we found that when the application server ends the stream 
(by sending a 0CRLFCRLF), the apache server starts sending and endless stream 
of 0CRLF bytes to the client.

Another observation is that although IE6 is totally incapable handling this 
flood from the apache server, IE7 is able to handle it elegantly.

We are facing this critical issue and any help in this regard will be greatly 
appreciated.

-Thanks.
