As I suspected, you are using remote mounts. Do you have any other devices in UD? I am working on some time outs that should keep UD from becoming completely unresponsive, but I'm not sure it will help in your situation.
I have several recommendations:
- For the time being, remove the preclear plugin. UD and preclear are connected in several ways and could be interacting negatively. Reboot the server to be sure preclear is completely removed. This will occur if you update Unraid.
- Update Unraid to rc5. There were some issues with earlier releases.
- Update UD to the latest version I will release later today.
Then see if you have any issues with UD hanging. If it hangs, I would just see if it times out. It may take minutes. Open another browser session and move on if you can. Don't try to stop the server or shutdown/reboot.
