Hello, We have a 20 CPU cluster which has AMD Athlon 2000+ MP processors. The cluster is relatively new and almost every week we loose one or two nodes due to the processors failing. I think the issue may be heat related, so we tried separating the nodes, increasing the airflow with a fan, and dropping the temp in the server room. None of these attempts have helped. We have also tried to replace the fans. Has anyone ever had a similar problem? How did you resolve it? Are pentium III more stable? Thank you in advance! Bonnie
