Since when has it been failing?

I’m unsure, they passed a while before we merged the attach fixes.

Reason for failure (if possible)

I assume that we have not written all logs on container termination and race between the CRI logger and child reaper. We probably need something to wait for the logs before exiting conmon-rs.

Anything else we need to know?
