Hi, I'm sorry, I forgot to post the version indeed.

The Python version I'm running is 2.5.2 (r252:60911, January 4 2009)
The Twisted version I'm running is 8.2.0, and I'm using the EPOLL-
Reactor (don't know if that matters)
The OS I'm running on is Debian version 2.6.26-2-686 (i686 GNU/Linux)

Is that enough info?

Best regards,
Dirk
