I am very curious about your problem, but I cannot help you with it with the incomplete snippets you have provided. Can you reduce your program to a smaller test program that produces this traceback?

Here is a guide to producing a useful example: <http://sscce.org/>

Thank for your help.

Thanks for reporting the bug. I hope you can provide us with enough information to get it fixed :).

PS: i use kqreactor.py from this branch http://twistedmatrix.com/trac/browser/branches/kqreactor-1918-3/

If you use the kqreactor.py from <http://trac.calendarserver.org/browser/CalendarServer/trunk/twext/internet/kqreactor.py>, does it make any difference, or do you still see the same traceback?
