yield-generator crashes with 'wrongly using an already spent utxo' #69

My yield-generator.py process crashed with this error:

done

The sys.exit line is preceded by a debug print with 'wrongly using an already spent utxo' in the code (I've not actually seen that message, probably because debug output was not enabled when I ran the script?).

You will need to post the entire log file so we can see the events leading up to the crash.

indent every line so it appears formatted

I will see if this crash happens again (I'm again running a yield-generator with the exactly same configuration) and post the log file if the crash is reproduced.

chris-belcher commented 9 years ago

It should still be in the log file even if you restarted. Unless the file was deleted or something

domob1812 commented 9 years ago

Unfortunately I don't have the logs anymore, and the crash did not occur again in the mean time. From your description, this sounds indeed like a very possible explanation. I'll close this issue here. If I see the crash again, I'll post my logs to the other issue.
