master

[lance6716]

maybe similar to golang/go#69629 because the fatal message is also fatal error: unexpected signal during runtime execution

[lance6716]

I'm not sure if we should upgrade github.com/dgryski/go-farm of pingcap/badger every repo to include dgryski/go-farm#21 . Just a guess.

[lance6716]

I have added "release-blocker" because I think release-8.4 is also affected. Let's wait some days to check if master branch has solved this problem
