Normale Version: SQL Error 1203 - max_user_connections
Du siehst gerade eine vereinfachte Darstellung unserer Inhalte. Normale Ansicht mit richtiger Formatierung.
Folgende Fehlermeldung hab ich schon seit längerem, diese tritt immer häufiger auf:

Zitat:MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1203 - User web1501 already has more than 'max_user_connections' active connections
Query:
[READ] Unable to connect to MySQL server

Hab den Support mal angeschrieben meines Hosters, ob er max. connection vielleicht erhöhen kann, dieser befindet sich in Amerika und gab mir diese Antwort:

Zitat:Thank you for contacting us. The max connection allowed per user is 15 and will not be raised. This is a setting set at the root level of the shared hosting server. This is to allow other users on the serve the same opportunity to connect to the server by not allow another to use all connections to himself.

What is happening is your MySQL user is connecting to the server and the query is taking too long. Ideally the query should take less than 1/2 second. You can review the /tmp/mysql_slow_queries to determine which query is running longer than normal and optimize it. If the tables are not indexed, this can take longer to query.

Another solution is to use persistent MySQL connection. Instead of multiple connections to the server by the same user, you have just one connecting to the server to run these multiple queries.

Ich verstehe das leider nicht so ganz, was und wie ich es optimieren muss, hat jemand eine Idee ???

Aus dem ich überhaupt nicht schlau werde, kann mir jemand vielleicht auf die Sprünge da helfen?

Meine aktuelle MyBB Version ist 1.6.0
PHP Version 5.2.13
SQL Engine MySQL 5.1.47

Hoffe, es kann mir jemand helfen...
Das MyBB baut immer nur eine Verbindung auf, d.h. es können gleichzeitig 15 Benutzer auf die Seite zugreifen. Wenn irgendwelche Codes weitere Verbindungen aufbauen, werden es natürlich weniger.
Also einige der Queries im Log scheinen mir vom Backup-Task zu stammen, denn etwas anderes gibt es nicht in MyBB das SELECT * FROM mybb_posts macht. Da musst du halt ggf. den Backup-Task abstellen und Backups mit dem phpMyAdmin des Hosters machen (sofern für den die Limits dann nicht gelten, ist bei manchen Hosts so).

Insgesamt klingt mir das aber nach einer ziemlich überladenen Kiste bzw. nach einem Freehost.
