I have a Fedora Rawhide running FAH v7 and it is now segfaulting all the time:

 FahCore_a4[1749]: segfault at 7fb7e4b08590 ip 00000000006d3767 sp 00007fb7f035df20 error 4 in FahCore_a4[400000+5e9000]

Current project:

Code: Select all

Project: 8004 (Run 94, Clone 3, Gen 194)

I've removed the core files, but it seems to be the latest FAHCore A4 available:

I just moved the work folder away and restarted the FAH client. It seems to work now:

If someone at PG shall want to investigate that faulty WU data then I can send it in.

The WU has been reissued several times and everybody seems to be getting an error after 0.01 days and receiving 0 points. It's what we typically call a "bad WU"

I'm changing the title and moving your post to the Problems with WU forum.

I have no reason to supect it has anything to do with either V7 or with Linux.

I have marked this WU as a bad one:

The WU (P8004,R94,C3,G194) has been reported as a bad WU.
