Wisconsin c4130-110433 becomes unresponsive frequently

[Wei Luo]

Hi,

I have the same issue stated in https://groups.google.com/g/cloudlab-users/c/Or-wYwEY5xM/m/KvUzmKbMFAAJ and reboot is required every 10 - 15min.

and I have tried all the network settings including both NetworkManager-wait-online.service and sudo systemctl disable NetworkManager but it is still unresponsive frequently. I previously have the same issue with Clemson c4130 (where I asked yesterday) but it is solved by disabling NetworkManager, however it is not working on the current Wisconsin Node. Thank you!

Here's my node information: c4130-110433

Unfortunately, there was nothing significant on the console, and the
console was unresponsive. I did a hard power off ; wait ; on, and it is
now booting up. Were you using all four GPUs? Maybe this is the
instability problem Leigh mentioned.

Hi David,

Thank you for the reply, but I was only using 1 GPU.

Best,

Hi David,

It is currently still unresponsive, I didn't try to login the node until now, but currently it is already unresponsive even when I don't login and use it.

Best,

Wei

There is nothing obviously wrong with it. I ran the diagnostics I could
remotely. We will have to schedule it out of service and have someone at
Wisconsin look at it closer.

I do notice you are running an X server on the graphics hardware. You
probably want to uninstall that. Probably not a problem, but who knows
what it might be suspending or tweaking on its own.
