I am using lxd move command to migrate a container. While this seems to be working and I can find that the container is running in the destination node, I noticed that in some cases, the background processes are not running. I can’t find a relationship between these cases for why this is happening.
The background processes are callback functions in a Python script running inside the container.
The issue is occurring in a ratio of approximately an error every 3 migrations. (No error in the logs, The process are killed silently).
Does anyone have an idea of the source of this issue?
The host nodes are running Ubuntu 18.04, I updated CRIU to the latest available version with no success.
Thank you in advance.
