Mysql Set Max_connections
Too many connections MySQL is telling you that it is handling the maximum connections that mysql too many connections flush you have configured it to handle. By default, MySQL will handle 100 connections simultaneously. This is very similar to the situation when mysql too many connections reset Apache reaches the MaxClients setting. You won't even be able to connect to MySQL to find out what is causing the connections to be used up, so you will be forced to restart the MySQL daemon to https://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html troubleshoot the issue. What causes MySQL to run out of connections? Here's a list of reasons that may cause MySQL to run out of available connections, listed in order of what you should check: Bad MySQL configuration Verify that you have set MySQL's buffers and caches to appropriate levels for the type of data you're storing and the types of queries that you are running. One quick way to check this information is https://major.io/2008/06/24/mysql-error-1040-too-many-connections/ via MySQLTuner. The script will tell you how well your server is performing along with the corrections you should make. Running the script only takes a few moments and it doesn't require a DBA to decipher the results. Data storage techniques Remember that MySQL works best when moving vertically, not horizontally. If you have a table with 20 columns, breaking it into two tables with 10 columns each will improve performance. Even if you need to join the two tables together to get your data, it will still perform at a higher level. Also, use the right data types for the right data. If you're storing an integer only, don't use a CHAR or VARCHAR data type. If your integer will be small, then use something like a TINYINT or SMALLINT rather than INT. This means MySQL will use less memory, pull less data from the disk, and have higher performing joins. Slow queries These are generally pretty easy to fix. If you have queries that don't use indexes, or if queries run slowly with indexes in place, you need to rethink how you're pulling your data. Should your data be split into multiple tables? Are you pulling more data than you need? Keep these questions in mind, enable the slow query log, and re-work your queries to

In addition, the phpBB main board seems to have had this problem at some stage. viewtopic.php?f=6&t=29086&p=190073&hili ... 40#p190073 What was done to fix too many connections this problem? Just increase the connections? Never happened to us on phpBB2. Thanks in advance.

But.... It's purely a hosting issue. You're on a shared server and the total number of connections for all the sites on it is going over a preset value. Ask your hosts to move you to a quieter server or up the limit.
