Ok, so tsample.zip is a test case for the original problem, right?
I can reproduce the problem on Linux also.
I can't make it crash (on Linux); what do have to do to make it crash?
If I access localhost:8080, I get log messages saying
2006-12-06 07:21:06,999 INFO servlet::__init__:1091 code 404, message File
not found
eloff: this report actually reports two problems (the I/O error, and the
crash).
Which of these are you having and have found lots of people having?
As for the traceback problem: this is due to the main thread terminating,
and
therefore the logging atexit handler getting invoked, which closes the
file.
Only then is the threading atexit handler invoked, which waits until all
non-daemon threads terminate.
As a work-around, add httpServer.join() at the end of your script.
I'll attach a patch that fixes this problem in the Python library.
File Added: threading.diff

I have this problem, I'm googling this and finding lots of people having
the same problem. I'm running python 2.5 on windows XP and using the
rotating file handler. I've disabled the logger in my application so I can
continue development.

to start application please use: src/py/run.bat
to get closed handler error (if you manage to start it)
please open your web browser and try to visit:
http://localhost:8080
You can change http settings in src/conf/development/robot.conf
sorry code is quite raw just started. :)

Can you provide a test case for either problem?

And I think python crashes on Windows if I try to use logger
from several threads.
