Subject RE: HTTP Connections Hanging

I'm surprised too, but trying to patch it is just not an option for me here.
So I guess someone with some more time than us, and maybe a bit more
familiar with the code, can take a look.  I'm also a bit concerned that that
last bug message states that it is not a critical issue.  I see this as a
major issue with anyone doing any real work with Axis.  

I'll take a look at the code and see what I can come up with.

Yes and no. I think the 'known issue' you're referring to may be my bug 
report:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=11296

The bugs are, I think, in the HttpSender code:
<http://cvs.apache.org/viewcvs.cgi/xml-axis/java/src/org/apache/axis/transpo
rt/http/HTTPSender.java?rev=1.94&content-type=text/vnd.viewcvs-markup>
<http://cvs.apache.org/viewcvs.cgi/xml-axis/java/src/org/apache/axis/transpo
rt/http/CommonsHTTPSender.java?rev=1.14&content-type=text/vnd.viewcvs-markup
>

Hope this points you in the right direction, but no, I never got around 
to writing a second patch.

When it came down to it, I don't understand all the intents in this code 
- particularly, what's supposed to be pooled where - and life is even 
more complicated with keepalives. I didn't have time then (or now) to 
figure it out.

I'm not sure why this doesnt bite everyone - possibly the sockets that 
are left open are closing when exceptions are thrown but the socket has 
dropped out of scope.
