Thinkphp3.1 cache failure

Thinkphp3.1 cache failure think3.1 + dwz system cache meaning write failed, permission and disk space check are no problem.

Deleting the cache can run normally for a period of time, and then this error occurs.
Porting to the new ubuntu system is normal for half a month.

This is clearly a failure to connect to mysql.

Restart ubuntu.

Check the error log

It should be because your mysql service is stopped or occupied by another program.

Check that mysql is started. this happens again in the morning, and it is restarted once.

Is it a legendary false death.

The best solution to reinstall mysql

Insufficient Memory

Find the reason, find the disk is deleted by the mysql-bin.00001 file occupies a lot of space, delete these files, restart mysql this situation, and then delete the mysql-bin.index to restart it will be okay
