I recently got 13 tasks and 12 of them failed. One completed successfully. The machine runs other Boinc projects successfully. A typical failure looks like this:

Did I get a bad batch, or is something else going on?

I had some rb_11 tasks get funky , mostly over running time, others took a walk on the wild side
It`l pass

Did I get a bad batch, or is something else going on?

Bad batch.
If you click on the link for the Work Unit, you can see that the other systems that tried to process those Tasks also errored out.

I agree about a bad batch. I have since had 5 work units complete successfully and no more failures.

However, one of my failures had another user complete it successfully.

I notice all my units run on my Linux machine end up valid.
And about half my units on my Windows machine are now coming up valid.
FWIW.
