Getting MySQL error max_user_connections on 4.6.0
April 14, 2015, 08:10:54 pm
Hi, I'm using CiviCRM 4.6.0 with Drupal 7.36 and I'm getting this error message a lot of time, even at the home page of CiviCRM

Code: [Select]
Array
(
    [callback] => Array
        (
            [0] => CRM_Core_Error
            [1] => simpleHandler
        )
 
    [code] => -24
    [message] => DB Error: connect failed
    [mode] => 16
    [debug_info] =>  [nativecode=User civicrmdb already has more than 'max_user_connections' active connections]
    [type] => DB_Error
    [user_info] =>  [nativecode=User civicrmdb already has more than 'max_user_connections' active connections]
    [to_string] => [db_error: message="DB Error: connect failed" code=-24 mode=callback callback=CRM_Core_Error::simpleHandler prefix="" info=" [nativecode=User civicrmdb already has more than 'max_user_connections' active connections]"]
) http://awesomescreenshot.com/0894tm8ob7

On /etc/mysql/my.cnf I changed max_user_connections from 5 to 10 and even to 100 but nothing, and also increased the max_connections value without luck.

If I work only on Drupal it works good, I can add, edit, modify or delete nodes, but when I click CiviCRM it takes years a lot of time to load a thing (if it loads anything) and then that error apears again (many of the times only the error, I mean, no Drupal menu, blocks, etc).

Also, from time to time, i got this on Drupal:

Code: [Select]
    Warning: ini_restore() has been disabled for security reasons en CRM_Utils_VersionCheck->pingBack() (línea 420 de /data/disk/o1/static/civicrm-4.6.0/sites/all/modules/civicrm/CRM/Utils/VersionCheck.php).

Can you ask your host about this? Adjusting the MySQL configuration should fix this.

Hi, as I told in the OP, I modifyed the MySQL variables and it's not better.

Take in consideration that that VPS host only about 4 sites max and they are not very popular (or had concurrent user connections) so is not a VPS load.

Have you restarted MySQL after editing my.cnf?  If not, you'll still have the old settings active.
You can find me at AGH Strategies.
Need help now?  Civi911 is your go-to for CiviCRM support.

Do you not have support for your VPS? Or a sysadmin who can help you?

Yes, sure, MySQL is restarted and I can see that it has taked the correct values:

Code: [Select]
MariaDB [(none)]> SHOW VARIABLES LIKE 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+
1 row in set (0.00 sec)

Code: [Select]
MariaDB [(none)]> SHOW VARIABLES LIKE 'max_user_connections';
+----------------------+-------+
| Variable_name        | Value |
+----------------------+-------+
| max_user_connections | 50    |
+----------------------+-------+
1 row in set (0.00 sec)

Also tried with max_user_connections = 100 or 200 or even 500 and nothing.

I don't know, but I would certainly ask them. :)
