What are you talking about is checking out the session_start () on the mysql-slow.log ()??

Are you sure this is mysql's "slow query log "?!
If the php stack trace appears in the slow query log of mysql, it is a strange event.

I have never noticed this before.
It is unlikely to be in the current log generation environment
The log information can only be inferred as follows:
Dump failed storage failed
Although I do not know the echo of the script information that mysql calls when php operates mysql
However, when the session is stored in mysql, this is completely possible.
Because the scheduling process is implemented in php (only the user-defined script is called back)
Session_start will trigger this process
General Inspection
In php. ini?
Session. save_handler = files
Does the program modify this value?
Session_set_save_handler
Are related databases and tables damaged?
