I just installed SmartCoin today and after playing with it, I have to say that it looks really great. You've really put a lot of polish on it.
Unfortunately I'm not having any luck getting my lockups detected. There's no relevant information in the SmartCoin logs, and the SmartCoin console just seems to stop running altogether. However, I can disconnect from screen and issue other commands so I know the machine isn't completely unresponsive. I can also run ./lockup.sh manually and it works fine.
What should I look at? Is there any troubleshooting information I can provide? Thanks!
