This happens to me from time to time. It seams to always happen when I am doing a number of concurrent things on the computer, and not limited boinc to take into account my activities, AND disk usage is at capacity from the nanohub tasks in progress. Bottom line, the message makes sense, the VM did not start the next task within the allotted time because too much was going on - on the computer.

The fix is very simple. exit boinc, and then restart boinc. Since the tasks in execution have the disk drive at capacity (temporarily) I prefer to suspend all tasks, underway (started) and not started before exiting boinc. That way when you restart boinc, it starts without having any jobs in que. I start the task manager, and release tasks as disk capacity is available. It usually only takes a 1 to 2 minutes.

Finally, I set my overall configuration to keep it under 75% CPU capacity, as I have the system set up to automatically overdrive. So even with 74% capacity, the overall CPU capacity on the computer is often in the 95+% range. I limit the number of tasks running by using

Options
Computer Preferences
Computing
Usage limits: x% of CPU's.

Currently, I had this set at 60% and I still got this message. Checking disk usage was pegged at 100%. Meaning the current batch of tasks from nanohub were slaming my disk drive.

No big deal. Shut down boinc and restart it.
