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
