Hello there, I'm running a Supermicro server with the latest CentOS 6.4 versions (kernel : 2.6.32-358.23.2.el6.x86_64) and the latest nvidia driver (331.20). A few minutes after using the GPU for doing some HPC calculations, the server crashes and reboots itself. This is happening every time. I know it will be rebooted but I don't know when. Sometimes it's 20 minutes after starting using it. Sometimes it's 2 hours. If I unplug the GPU card and put some stress on the server, it works ok. So I suspect there's a bug in the kernel/nvidia driver. I can't find any messages on /var/log/messages. What should I do ? Should I file a bug on the centos bugtracking system ? Is there anyway I can gather more information ? The server is in a remote location so I have a hard time accessing the console. Thanks.
