I've found a simple repro case so I reported https://jira.mariadb.org/browse/MDEV-17852 /Staffan On Mon, Nov 26, 2018 at 9:14 PM Staffan <solsson@gmail.com> wrote:
Hi,
I've tried to change a user's max_connections after the limit has been reached (connection attempts return "has exceeded the 'max_connections_per_hour' resource").
With MariaDB 10.2.18, running using the official docker image, we have "select @@max_connections;" returning 100.
We have a user created "WITH MAX_CONNECTIONS_PER_HOUR 50".
Now if we bump in to this limit I fail to allow more connections by increasing it. I've tried the following methods (using both 0 and a high value):
ALTER USER 'site_devkit_live_index'@'%' WITH MAX_CONNECTIONS_PER_HOUR 0;
UPDATE mysql.user SET max_connections = 0 WHERE user='site_devkit_live_index'; FLUSH PRIVILEGES;
GRANT USAGE ON *.* TO 'site_devkit_live_index'@'%' WITH MAX_CONNECTIONS_PER_HOUR 0;
The following indicates that the updates work:
USE mysql; SELECT host, user, max_user_connections, max_connections FROM user;
I've also tried deleting and re-creating the user.
What would it take to make these updates affect the current instance? We'd like to avoid restarts.
