I have been trying to setup CRIU v3.13 inside a privileged docker container (A dockerized CRIU Image is bundled as part of the Dockerfile on an Alpine Linux Base) to checkpoint a certain process. The containers run inside a Kubernetes cluster on a fresh install
of Ubuntu 20.04 LTS.</div>

I have done some sanity checks, namely running the `criu check` command from within the container. Apart from `criu check`,<span class="" style="color:rgb(0,0,0)"> I have checked for various privilege accesses and all come back positive. </span> </div>

I am currently trying to get the `simple loop` example <span class="" style="color:rgb(0,0,0)">(</span><a href="https://criu.org/Simple_loop" class=""><span class="" style="color:rgb(255,202,0)">https://criu.org/Simple_loop</span></a><span class="" style="color:rgb(0,0,0)">) </span>working.
After following the instructions, I see that dumping the process fails with <span class="" style="color:rgb(0,0,0)">error code </span>-1. </div>

I haven’t had much success in finding a solution to the problem in the GitHub issues, and I’d really appreciate it if you could point me in the right direction.</div>
