my linux node is also constantly crashing. ah. I wish at least whitj came back and started fuddling with this
The code on the main branch was crashing for me on Linux too. I used the basic branch and that has been working fine.
git clone -b basic https://github.com/OpalCoin/OpalCoin.git
Use the basic wallet code. We removed some of the addons which were causing some issues. Please let me know if you are having issues and if you can send me your debug logs. I will look at these issues as they are bought up.
