Thanks for your advice! I got the error message and the pstack result screenshot from one of our client. I will try to use some OCR tools to convert the image to text next time.
For the questions: 1. The binary is built without race detector flag. I have checked it. 2. We do not use cgo. I will check if there is any unsafe package. Unfortunately, I can not reproduce this problem. This is the first time and the only time I meet it. Thanks!
