That goes *double* for threads started with start_new_thread; if you start threads that way you will have problems with clean shutdown as well. If you have work you want to do in a thread in Twisted, use reactor.callInThread. http://twistedmatrix.com/documents/10.0.0/api/twisted.internet.interfaces.IReactorThreads.html#callInThread If, for some reason, you needed to tell a transport to disconnect from a thread, the right way to do it would be to call reactor.callFromThread(transport.loseConnection). http://twistedmatrix.com/documents/10.0.0/api/twisted.internet.interfaces.IReactorThreads.html#callFromThread However, this is still wrong, as there's no need to spin up or manage threads in order to run timed events in Twisted. Bottom line: don't use threads. If you think you need to in order to perform some basic task, there is probably a Twisted API you haven't learned about yet. > Can anyone direct me on the proper way to kill a connection from the server > end in a clean manner? If you want to check the connection every 30 seconds, use a LoopingCall that calls your 'check' function every 30 seconds, to check the activity flag and call loseConnection if necessary. http://twistedmatrix.com/documents/10.0.0/api/twisted.internet.task.LoopingCall.html You should also know that until <http://twistedmatrix.com/trac/ticket/78> is closed, your connection won't be "killed" so much as it is "shut down"; the socket will wait until all of its remaining data has been sent (or the TCP-level timeout has passed) before closing. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
