Xeon(R) CPU E5-2620 still useful?

[parkut]

A friend has been running his repurposed server for years, but now fails jobs immediately. I wonder if the CPU is still capable?

None of the above shows that it is failing.
If CPU fails a WU, there would be trail in the logs showing where a CPU starts the work and fails. Your logs show none of that

What project is it trying to fold? There have been certain issues with 12474 on Linux that is crashing in a way that looks like the core is just being paused (returning interrupted instead of failed): viewtopic.php?p=370137

The issue is being investigated internally.

To answer the question in the topic though, yes, the E5-2620 is still useful and probably will be for quite some time. Newer hardware would be faster of course, but there are people who fold on much older and slower systems than a Xeon from the Sandy Bridge generation and they still get work done and aid research.
