Answer 1

If you get a Too many connections error when you try to connect to the mysqld server, this means that all available connections are in use by other clients.

The number of connections permitted is controlled by the max_connections system variable. Its default value is 100. If you need to support more connections, you should set a larger value for this variable.

You should ask your system administrators to do these changes only when necessary.
