HELP!

Running Fedora 32. FAH had been working well then the FAH Control disappeared after update.
Was able to get FAH Control back (Python 2-3 issue) but now the following cycles once a minute
on my machine. Was turning 72,000 PPD and now I am running 32. At this point I am at the limit
of my understanding of software. Any help would be appreciated.

Project is 14524 333,5,22

Thank you! Kirito ( I broke all the hyperlinks in this )

Try setting the number of CPU threads to a lower number like 18 after pausing. Restart after a minute to allow the setting to save. It may also work on 21 threads, and almost certainly will work on 16. They have been having recurring problems with this project assigning to CPU thread counts that it has problems with, settings keep reverting.

Thank you!

I had to turn it down to medium speed at 12 of 24 cores to get it to keep running.
Once this job finishes (tomorrow sometime) hopefully I can go back to full speed.

Thank you folks for helping me out.

There will be times when what you're calling "full speed" will be difficult to fulfill. You may find that long-term you'd be better of with two slots of 12 or one of 16 and one of 8 threads. The slider was developed when most CPUs had 16 or less threads and it has not been updated.
