Some WUs are faulty but we have no way of checking if that is one of them or not unless it is reassigned and then completed by someone else.
Some have been able to stop the client just before the error and restart it and it seems to skip the error.
Others have been able to run qfix and report the partial result. The client then moves on to another WU.
Others have simply deleted the WU that they know is going to fail and repeated that process until they got something else. We don't recommend deleting a WU, but in this case it's justified.
Thank you for the reply, Bruce.
I just let it do what it normally does. This time it retried only once more after the initial EUE.
Then I was assigned another 2653 WU.
Perhaps the dreaded thing has died, nevermore to return!

This WU appears to be faulty. Each failed iteration is taking over 10 hours of wall clock time. It is a shame to waste so many crunching cycles on this. Please advise on an appropriate course of action.
Thanks!
