MySQL 1587

This error occurs when the maximum number of open files has been reached while attempting to purge binary logs.

How It Affects Your App

The error ER_BINLOG_PURGE_EMFILE indicates that the application has reached the maximum number of open files allowed by the operating system. This can cause the application to become unresponsive and unable to process requests. It can also lead to data loss or corruption as the application is unable to write to the binary log. This can have a significant impact on the application's performance and reliability.

How To Fix

1. Check the error log for the MySQL 1587 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL process list to see if any processes are running that could be causing the error:
$ mysqladmin -u root -p processlist
4. Check the MySQL user table to see if any users have been created that could be causing the error:
$ mysql -u root -p -e "SELECT * FROM mysql.user;"
5. Check the MySQL grant tables to see if any privileges have been granted that could be causing the error:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
6. If the issue persists, restart the MySQL server:
$ service mysql restart
