Something in your program broke the reactor. Or you found a bug in the
reactor which causes it to break itself. It doesn't seem likely anyone
will be able to figure out which or how without seeing your actually
source, though. If you can provide a minimal example of this, and it's
a bug in Twisted, we should be able to fix it. This is a pretty central
piece of functionality, though, and it gets exercised all the time, so
chances are good that there's something in your program that's causing it.
The specific problem is that a pipe file descriptor, internal to the
reactor, has been closed. The reactor is not expecting this to happen,
and it shouldn't, since it never closes it.
