[Bug] kernel panic #2467
Description
Verify steps
- I have read the documentation and understand the meaning of all the configuration items I have written, rather than just piling up seemingly useful options or default values.
- I have carefully reviewed the documentation and have not resolved the issue.
- I have searched the Issue Tracker for the issue I want to raise and did not find it.
- I am a non-Chinese user.
- I have tested with the latest Alpha branch version, and the issue still persists.
- I have provided the server and client configuration files and processes that can reproduce the issue locally, rather than a sanitized complex client configuration file.
- I provided the simplest configuration that can be used to reproduce the errors in my report, rather than relying on remote servers or piling on a lot of unnecessary configurations for reproduction.
- I have provided complete logs, rather than just the parts I think are useful out of confidence in my own intelligence.
- I have directly reproduced the error using the Mihomo command-line program, rather than using other tools or scripts.
