Issue with Project: 8049 (R 777, C 4, G 107) and FAH Core A4

Posted: Fri Nov 09, 2012 2:08 pm

Since yesterday FAH Core A4 crashes (Windows APPCRASH) while processing Project: 8049 (Run 777, Clone 4, Gen 107). After confirming the Windows message the core starts new and continues folding.
Today, after the first crash, I stopped folding using FAHControl and deleted the folder "C:\Users\myUsername\AppData\Roaming\FAHClient\cores\www.stanford.edu\~pande\Win32\x86\Core_a4.fah". After a restart FAH has downloaded FAH Core A4 again and continued folding, but now Core A4 crashed again. Is it the core itself or does the WU cause the crash? Should I finish the WU or dump it?

Here is the latest logfile:

Re: Issue with Project: 8049 (R 777, C 4, G 107) and FAH Cor

The WU has been completed by another folder:

Hi xxxxxxx (team xxxxx),
Your WU (P8049 R777 C4 G107) was added to the stats database on 2012-11-08 17:08:08 for 1338.9 points of credit.

In this case it should be okay to dump work/00.

You might want to reboot your computer as well before restarting the client.

Apparently neither.

Part of the original design of older clients included a feature that attempted to answer your question. After certain failures like that, the client assumed the WU was corrupted during download so it re-downloaded the WU. After several more failures, it assumed the FahCore had been corrupted during download so it redownloaded the FahCore and restarted the WU. Occasionally, one or the other worked and the WU was completed. More commonly, the fault was neither so the WU was then assigned to someone else.

Error 255 = 0xff is a generic error code that probably points to a hardware fault (memory??) which is pretty much confirmed when it was reissued and completed somebody else.

Ok. FAH dumped the WU and downloaded another one (Project: 8055 (Run 1326, Clone 3, Gen 30)). Let's see if the core will continue to crash.
