Hi,

I have an old Dell machine running 24/7, not overclocked in any way. This specific unit caused segfault at least 20 times. Here's a log after restart:

Hello, nyanthiss, and welcome to the Folding@Home forums.

I checked the database for the WU, Project: 7610 (Run 105, Clone 0, Gen 75), and found one problem return of this WU, but also two successful completion/returns so you can be assured this was not a bad WU.

Hello,

Thanks for the reply. Have to admit i'm a bit confused now Could it be a bad WU download ? Should i just forget about it ?

[sortofageek]

It could be a hardware issue, a bad download or some other glitch. If you don't continue to have problems with that particular client, I wouldn't worry about it.
