Given the lack of activity, I am going to assume that this has been fixed in
later tcnative versions. It certainly sounds like some of the issues seen in
earlier releases.

As always, if you still see this issue with the latest stable releases then
please re-open and provide the steps to reproduce.

Given the trouble we have had re-producing this, could you test with 5.5.27 and
tc-native 1.1.16 in case one of the many fixes since 5.5.20 and 1.1.7 has fixed
this.

I have the same effect. Sometimes page is not loaded completely. Sometimes the
same pages are loaded twice, means: Page is delivered let's say for 70% and then
the complete response-content is delivered another time in the page. Effect:
Double Response in page. 

Number of characters until the response is repeated(in my example case): 204613.
The page is utf-8. Other cases were 221656, ...

We have a JSF/Hibernate application. 
Our environment: Linux(don't get the effect on windows); on Linux we have
AJP/1.3 and apr1.2.2; tomcat version 5.5.20;

Unfortunately the behaviour in our case is nondeterministic. :-( Seems to depend
on loading time of jsp. The bigger the page the higher the possibility to get
the strange behaviour.

Looks like this is still an issue with 5.5.15. Here is a further observation:
The problem doesn't occur when connecting from the same machine, but only when
connecting from a remote machine (tested Windows to Linux).

Sample telnet session:

GET /test/test.jspx HTTP/1.0

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: application/xhtml+xml;charset=UTF-8
Date: Thu, 23 Feb 2006 23:56:37 GMT
Connection: close

[snipped lots of data]
This is a

Connection to host lost.

I've added autoFlush="true" and buffer="8kb" to the jsp:directive.page element
(though I believe that's the default anyway), no effect.

If someone can confirm that the same test page can be retrieved fine from their
own installation (remotely), I'll try to dig deeper...

(In reply to comment #6)
> Content-Length: 22858 proves you are using response.setBufferSize.

Please have a look at the attached test application; it's a simple jsp page, no
response.setBufferSize in sight!

Content-Length: 22858 proves you are using response.setBufferSize.

It seems that the problem can't be reproduced on Windows. Perhaps I did
something wrong during setup? I have apr-1.2.2 installed.

A bad bug report ... The header returned gave away you were using a large
bufferSize (which BTW I consider an inefficient waste of memory), however.
