, after restart, the system log is normal, no error found.

postscript:
this error does not seem to affect the use of the operating system and software, found before the error, the computer performance is very good, all kinds of programs normal. When I checked the system log, I felt uncomfortable seeing the Red Cross, which immediately aroused my curiosity.
