we often have this problem when the CPU runs out of network sockets. It reminded me we still had at MVME2431 on the left arm. We will try to swap it with a newer model with more memory and more sockets.
For now I commented the scaler server to see if that helps. I managed to start and end a run after the reboot but scalers are down for now.
If the runs still hangs let me know that could mean the problem is something else.
