Work units dumped when PC shutdown or reboot

Tropical Snowman · Post by **Tropical Snowman** » Tue Oct 28, 2025 11:47 am

Hello there, I'm on Windows 11 and Folding always dumps work units when pc reboots or shutdown normally. Weirdly enough, if there's a sudden power loss, WUs are not lost and start again from the last checkpoint.

Windows gives me the brief warning "This app is preventing shutdown", showing that Folding would need some more time - I guess.
Exiting or pausing FAH before shutdown avoids the problem altogether, and that's how I've been doing.

I wonder:

Is it an expected behaviour?

Can I fix it?

Windows 11, Ryzen 7 7700, 32gb DDR5 ram, AMD RX6700.
Here's the log:

Code: Select all

11:01:31:I1:WU651:Checkpoint completed at step 350000

11:03:16:E :WU642:Core exited with an unknown error code 1073807364 which probably indicates that it crashed. Dumping WU

Thank you for you attention.

Yes, this is a bug, and it has been fixed in the latest alpha.
Before that, it is advised to pause before rebooting the system.
Linux client doesn't have this issue.

Okay, thanks. I'll go on pausing before shutting down. Thanks.
