Restore fails with the error `Can't connect inet socket back: Cannot assign requested address` or `Can't restore 0x7f1164021000 mapping with 0xfffffffffffffff4`

I ran into a problem during process restore. I am starting a process in a separate session using setsid. I use criu-ns to perform dump and restore. The restore did not work as expected after several times of successful dumping and restoring the same process. These errors are really rare, but it would be better to know what is going on there.

0xfffffffffffffff4 is ENOMEM here, isn't it?

Can't connect inet socket back: Cannot assign requested address

That looks like some other process is using same port you want to restore with, to fix this use container environment with criu support (e.g. podman) to isolate your app from all others.

I met this problem Cannot assign requesed address recently. The reason is that the ip adress hasn't been configured.
