php, mysql - Too many connections to database error

Question

Good day to all. I have an odd error. I have created a chat that works like this:

• questions/answers are inserted into a db
• every 2 seconds an ajax re

Answer 1

The error SQLSTATE[HY000] [1040] Too many connections is an SQL error, and has to do with the sql server. There could be other applications connecting to the server. The server has a maximum available connections number.

If you have phpmyadmin, you can use the 'variables' tab to check what the setting is.

You can also query the status table like so:

show status like '%onn%';

Or some variance on that. check the manual for what variables there are

(be aware, 'connections' is not the current connections, check that link :) )
