MySQL 1775

This error indicates that the global number of connections has been exhausted. It is a warning that the maximum number of connections has been reached and no new connections can be made until existing connections are closed.

How It Affects Your App

MySQL 1775 ER_GNO_EXHAUSTED indicates that the application has exhausted the global number range for the table. This can cause the application to fail to create new records, as the global number range is a unique identifier for each record. This can lead to data integrity issues, as records may not be properly identified or linked. Additionally, the application may not be able to perform certain operations, such as sorting or searching, as the records may not be properly identified.

How To Fix

1. Check the error log for the MySQL 1775 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 queries are running for a long time:
$ mysqladmin -u root -p processlist
4. Check the MySQL user privileges to see if any users have excessive privileges:
$ mysql -u root -p -e "SELECT User, Host, Password FROM mysql.user;"
5. Check the MySQL table structure to see if any tables are corrupted:
$ mysqlcheck -u root -p --all-databases
6. Check the MySQL query cache to see if any queries are taking too long to execute:
$ mysqladmin -u root -p extended-status | grep -i "query_cache"
