A strange error message

[jfongattw]

I have a top level function main() something like this, it was called when script starts:

def main(input_str): for c in input_str: ... pfsm.send(achar) time.sleep(0.01) ....

where pfsm is state machine, achar is an event. It runs correctly.

when the line of the sleep() was comment out, I get a strange error:

Fatal Python error: could not acquire lock for <_io.BufferedWriter name=''> at interpreter shutdown, possibly due to daemon threads

Hello,

Thanks for feedback. Sorry for late reply, I had a few personal things to attend to.

As for the error, is your application terminating some time after sending the event to pfsm?

Best regards, Nenad

Since I have had a second look at this issue it seems to me it is somehow related to shut-down while the state machine is still being executed. Since this is an old issue and you probably have already fix it by now I'm closing this issue. If you still have the problem and/or have the will to still correct the issue please feel free to open a new issue. Thanks!
