This WU , and many more like it, were sent to my computer with a very short deadline, resulting in everything running at "High Priority" in order to try to get them all done before the deadline. In order to reduce the work overload, I aborted about half of the tasks.

There are two problems here.


  • "High Priority" causes D@H to incur major debt with respect to other projects.
  • The abort of a task gets counted as an "Error". Since a WU is allowed no more than 1 error, the WU will not be sent out again.

Hello Steven,

I'm looking at your problem right now. I cannot understand why it did hapen. Our applications use the default priority and the deadline for all workunits of 1hiv was more than 1 week, which is plenty of time since they take only a couple of hours to complete. I will try to recreate the conditions in which this may be happening, and if I find a bug I'll fix it.

Thank you

Timing and scheduling are part of the problem, but the biggest part is that a single user can cause work units to never be calculated by simply aborting them .

There are two solutions that I can think of . . .


  • Increase the number of error results allowed on each WU to at least 2
    • - OR -
  • Do not count an Abort as an Error.
