CRIU checkpoint failure: Cannot checkpoint container

The environment and steps of the test are as follows:

Among them, criu check--all had an same error , but it also occurred on my another computer (3.10 kernel), but it didn't affect the checkpoint. The example of deploying containers is the official example of the CRIU reference: https://criu.org/Docker

Thank you very much！
