I guess this is an issue whicht has to be fixed by the project owner. I merely want it to announce this way to open the opportunity for.

Greetings

Can you cancel that project and do a new one?

Thanks for the report. I forwarded the information to the project owner.

contrib854> is there a reason for you to run only with 3 threads ? You could temporarily fix the issue by running 2 or 4 threads.

FaH did this automatically.

contrib854> is there a reason for you to run only with 3 threads ? You could temporarily fix the issue by running 2 or 4 threads.

3 threads is the proposal made by FaH. I have a 4 core CPU. 1 thread is for the management of the FaH slots which leaves 3 threads for the FaH CPU slot. Because this would slow down the computation of other projects as well I am reluctant to resort to 2 threads.

If you have a NV GPU, it's often better to leave 2 threads free to feed it efficiently.
