Yes, it works. THX Leo

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: http://com-os2.ms.mff.cuni.cz/temp/example.log.gz (2767808B)
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
