Hi, let us talk over the list please, I don't like discussing stuff over the tracker.

In my system (Ubuntu > 7.10 Linux izzy 2.6.20-16-generic #2 SMP Sun Sep 23 19:50:39 UTC 2007 i686 > GNU/Linux), the select call was raising an interrupted system call > exception so often as to make the recording server unusable. Very strange. If that happens, it could also happen during other systems calls like ioctl which will cause a lot of trouble. > As far as being unable to kill the record server, I don't see this issue > with the patch in place: > > $ ps aux | grep py > root 26061 0.0 0.3 14160 7680 ?

I did not try the recordserver, I don't use 1.7. For my 2.0 testing apps, I could not kill the process anymore. Duncan: is the code using unix signals? Is this the code running kaa.notifier as thread inside twisted? If the later is true, this could explain why I never saw this and why kill still worked. In that case we need a special fix for the threaded code. Please try to only catch that signal in nf_thread.py in run around | nf_wrapper.step(simulate = True) > Maybe on your system, you need kill -9 kill -9 won't give me a clean shutdown.
