Hi,
In my application, some background threads are being created. But when a
thread finishes up its work, a strange exception is thrown:
The callstack doesn't show any part of my application code.
=====================================================================================
Traceback (most recent call last):
File "C:\Python24\Lib\site-packages\zope\server\taskthreads.py", line 48,

=====================================================================================
My worker thread are created using threading.Thread based classes.
Does anybody throw some light about this error?
Thanx for your help.
With regards,
