I was doing a bulk load two days ago. for my sub-task board. which I've done many times. The data loaded fine. But my subtask board has never responded. the backlog and Kanban work fine. It gives an error too many files are trying to load. Other team members are now getting the same message on the same board.
We I navigate to that page it fails immediately.
I've rebooted and connected with WiFi and Ethernet.
I've attached a screen shot.
Thanks, 
Steve Bailey
