In my
previous post I described the problem.
This problem occurs stably on three computers at intervals of approximately 15 minutes.
cgminer 3.2.0
Now, for reasons of clarity, cgminer was started with the - disable-gpu
Here I found the instructions to provide more information about the problem.
The following information from the bt full command:
