Test failure is unlikely related.

Hello Nikolai, thanks for the merge.
I've received a bunch of notifications about PR test failures, e.g.

[ClickHouse/ClickHouse] PR run cancelled: PullRequestCI, Attempt #8 - sequence state fix (02d2f5c)

Does it mean that something related to the PR went wrong, or it is kind of normal?
