Hi, @dingyalin. I'm Dosu, and I'm helping the Kratos team manage their backlog. I'm marking this issue as stale.

Issue Summary:

• A data race condition is reported in the config watch functionality of the Kratos framework.
• The race occurs between the SetLogger and Infof functions, accessed concurrently by different goroutines.
• The issue is currently unresolved, and there have been no comments or additional activity.

Next Steps:

• Please confirm if this issue is still relevant to the latest version of the Kratos repository. If so, you can keep the discussion open by commenting on the issue.
• If there is no further activity, the issue will be automatically closed in 7 days.

Thank you for your understanding and contribution!
