Adam,
There are two layers of code on top of the HttpClient (both I know very little 
of), so it is really difficult for me to make any soft of informed guesses 
about a possible cause of the problem. But what I can see from the logs and the 
code snippets makes me fairly confident about a few things:

* I do not see connection being released in the log. I do not why this happens 
but this is what I see.
* In VFS the connection release is supposed to be triggered by closing the 
input stream. The consumer of the VFS code must ensure that the input stream is 
closed under all circumstances (including abnormal circumstances).
* Please consider downgrading to HttpClient 2.0. CVS HEAD is currently in a 
state of flux and should be considered experimental. 
* I can well imagine that there is a bug in the multi-threaded connection 
manager code that is triggered by some sort of less usual combination of an 
HTTP HEAD followed by 301, or probably non-compliant HTTP HEAD (that returns a 
body) followed by 301. But unless the issue is isolated and is reproduceable 
with a smaller, more manageable test case, it is really hard to tell

Oleg
