How It Affects Your App
MySQL 1094 ER_NO_SUCH_THREAD can cause an application to fail to connect to the database. This can lead to data not being stored or retrieved correctly, resulting in incorrect or incomplete information being presented to the user. Additionally, the application may become unresponsive or crash, leading to a poor user experience.
How To Fix
1. Identify the source of the MySQL 1094 error. This can be done by checking the MySQL error log for the exact error message.
$ tail -f /var/log/mysql/error.log
2020-08-20T14:45:45.123456Z 0 [ERROR] 1094 You are not owner of thread xx
2. Check the user privileges for the user that is trying to execute the query. This can be done by running the following command:
$ mysql -u root -p
mysql> SELECT USER(), CURRENT_USER();
+----------------+----------------+
| USER() | CURRENT_USER() |
+----------------+----------------+
| root@localhost | root@localhost |
+----------------+----------------+
3. Grant the necessary privileges to the user. This can be done by running the following command:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
Query OK, 0 rows affected (0.00 sec)
4. Restart the MySQL server. This can be done by running the following command:
$ sudo service mysql restart
