Segmentation fault

when I run: sudo criu restore --shell-job --restore-detached --images-dir demo

I keep getting this error:

Error (criu/cr-restore.c:1480): 2001 killed by signal 11: Segmentation fault
Error (criu/cr-restore.c:2447): Restoring FAILED.

I am not able to restore the checkpoint. Is there something I am missing. I followed all the steps for the same counter example.

Likely an issue with your CRIU version, which are you using and could you try a newer one?

I used v3.19 and I was able to successfully run this step. but I got another error:

Command I ran:

cuda-checkpoint --toggle --pid $PID

Error:

Error toggling CUDA in process ID 19897: "OS call failed or operation not supported on this OS"

Is there a reason why this is happening?

I also encountered this error. I used sudo to execute this command, and the error was solved. Therefore, I suspect that it may be due to insufficient permissions that caused this error.

You'll need to use sudo for most cuda-checkpoint operations as well as having access to /proc/
