Our DD agent is dead w/ the below log, but it is unclear for us to do triage.
Usually 256 EXIT CODE in Linux is general error and thus we cannot get any clue on why DD agent is dead.

We are running the DD agent on K8s and thus we can see "KILLING CONTAINER".
Can any expert in DD agent help us to do triage?
Thx.
