ClientAbortException means the user canceled the download (the 'client

Yeah, that's the answer you'll find most frequently if you spend time
Googling for that exception, but anecdotally you'll find that more times
than not, there's no evidence of the browser being closed or the client
aborting (pressing Stop) while a page is loading. There's definitely
something else going on in a great many cases, and I'm at least happy to
know that I'm not alone in not having found the real answer yet :

Folks;
still messing around with an error like this: In our system, we offer
customers a service to download files using a servlet. Some weeks ago
(more or less when I considered switching to tomcat 6.0), the following
error frequently started to show up in my log files:

whereas I see a "ClientAbortException" caught by my applications
exception handling mechanism. So far, I haven't been able to track this
down, that's why I am kindly asking you for your skilled advice.
What did I do so far trying to get hold of this:
- Tomcat runs on a machine in the LAN, fronted by an apache2 httpd.
- The error does appear both running tomcat 6.0.13 and 5.5.23.
- I initially was using mod_jk 1.2.29 and switched to mod_proxy and
Proxy/ProxyReverse setup just to make sure, and the error appears
no matter whether using mod_jk or mod_proxy.
- Right now, I am using apache2 prefork mpm, played around with
different mpms just to be sure it's not an error related to apache2
itself, but this also didn't really change anything.
- apache2 logging doesn't show any messages whenever such a
"ClientAbortException" is thrown.
- Customers, however, reported that whenever such a situation happened,
the files downloaded were either 0k sized or corrupted.
And I'm whole-heartedly clueless by now.... :( Is there anything I
forgot to double-check? Using the latest JDK, no tcnative, running
Ubuntu Linux 6.06.1. Applied pretty much every solution attempt I could
come up with using google, including tweaking the HTTP connector setup
in server.xml, removing tcnative, using mod_proxy instead of mod_jk -
no success. Does anyone around here have any more ideas on how to get
hold of this?
Thanks loads in advance and bye,
Kristian
