I have a mysql server5.6.

Always output error information to the error log file.

[ERROR] Failed to write to mysql.slow_log.

I have no problem with disk and memory and os,Is there any other reason？

Answer 1

If space is not a problem, check whether the table is too large and exceeds the system single table limit? Or permissions? If it only happens occasionally, maybe you have encountered a bug. Mysql5.1 seems to have this bug. It is better to use file records
