Gentlemen: I am trying to use the twisted perspective broker in a client that repeatedly makes remote calls to a twisted server. I'm running a MAC OS X. I create a client object, which calls reactor.connectTCP(), builds the deferred object to make the remote call, calls reactor.run(). A deferred callback eventually reactor.stop() and returns the correct answer. Now I need to do this again, so I create a new client object, etc., which goes through the same procedure and eventually call reactor.stop (). Again, I get the correct answer from the remote call, but the reactor keeps running. In other words, the statements after the reactor.stop() execute, but the statement after reactor.run() is never reached. The client hangs. What am I overlooking?? -- perplexed
