Okay, I think I have the fix. It seems that there is a problem
releasing connections that throw an exception then closing the
response stream. Leo, please try out the patch attached to
http://issues.apache.org/bugzilla/show_bug.cgi?id=22841.

Well, I've narrowed it down a little. It seems that connections
made to the host below are not being released. Coincidentally all
of these hosts use chunked encoding. I don't know if this is the
cause, but it seems suspicious. I'm going to run some more tests.
Attached is the perl script I'm using to find unreleased connections.

Hi Leo,
Well, I've done some analysis of the log file and I think I have a
few answers. It seems that a few connections are not being
released. To be exact, 47 connections are not released. 42 of
them get reclaimed by the garbage collector, but the other 5 remain
in limbo. We'll need to do some more work to figure out why these
connections are not released. I wrote a quick perl script that
analyzes the log file, which I will post tomorrow. That's all for
tonight. I'm going to get some sleep. More to come tomorrow...

Hi Mike,
you have it here:

I set maxTotalConnection=5.

Hi Leo,
Attached at the bottom of my message is another log4j
configuration. This should considerably decrease the amount of
logging. It also keeps all of the logging info in a single
file. To successfully debug this case we will need all of the
logging data for a particular session. In conjunction with this
debugging we also need to reduce the time it takes for this
error to come up. As I suggested in my email a few day ago you
should also try decreasing the number of total connections via
MultiThreadedHttpConnectionManager.setMaxTotalConnections().

Hi Mike,
I've never used log4j and I missed your logging.html page, thus
I tried my simple config (see below). Unfortunately, I cannot
reproduce the bug easily (- no test case yet) - the robot has
to run more than 6 hours.
BTW: I had to rotate log files due to a huge volume of data, so
you can see last 30 log files. I guess the format is obvious
from the config file below. If you cannot find what you need,
please, edit my log4j cfg file and I will rerun it again.
Thank you
Leo
