Woke up to a couple of these errors in my client, any ideas? Nothing has changed on my computer.

Please note that error message means that the WU assigned to you was not able to be partitioned across your CPUs since the assigned WU was too small. Thus, it encountered the Domain Decomposition issue. Your client will simply pick up a new WU and carry on.

There are plans to ensure that errors like this are handled more gracefully by the client using FahCore_a8.

Excellent, thank you for the explanation. Terminology had me confused.
