What I did
Issue introduced in #3170
lag_keepalive invokes teamdctl which is a wrapper around docker exec -i. This command is known to not work togather with timeout and similar issues have been fixed before - #1904
How I did it
Add
--foreground
option for timeout to receive TTY signals.How to verify it
Run warm or fast reboot.
