Before I post the log, I'd just like to point out that I'm using the Notfred client and that I understand it's not widely supported. There's also that the error is fairly new to Folding@Home. I'm posting the log so hopefully that the mods and admin and folding team can determine the cause of the error and a solution to it. Google says that it seems to be based on a bad checkpoint though.

I'm not sure what Error 0xff is, but if you're right about it being a bad checkpoint, I'd guess that whatever storage media that the files are being written to is too small. How much free space is there in the partition in which FAH stores its work files?

[geokilla]

Um I run the Notfred client, so it's a diskless folding client. The partition where the VMX files are located is over 80GB big. As for the place where it stores the F@H files, I have no idea. Diskless folding has its problems I guess.

This post and the few after it in the Third Party Applications section of the forum may help to solve your problem. I too have run out of memory in the VM when running notfred's on a Windows host machine. it's easy to increase the VM's RAM but not obvious how to increase the size of the VM's virtual hard disk. I get the impression that most people using notfred's app (note that it ISN'T a client; the client is Stanford's) use the USB stick version.

To stay on topic, let's save this thread for other reports of trouble with the actual work unit, and redirect discussion of the notfred app back to the appropriate thread in the Third Party Apps forum area. Many thanks!
