Any luck getting to the bottom of this? I had another lock up last night and symptoms seem to be similar. This time instead of reboot the entire PI I killed the OpenRemote process and restarted it and it started operations again.
If you need me to try anything or capture any other information that may help troubleshoot better let me know.
Thanks
Checking to see if you had a chance to look into to this. A couple of days ago I had to restart the controller again due similar lock up issue. I have the log files saved if you need them.
