A.2.6 `Too many connections'
----------------------------
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 allowed is controlled by the `max_connections'
system variable. Its default value is 100. If you need to support more
connections, you should restart `mysqld' with a larger value for this
variable.
`mysqld' actually allows `max_connections+1' clients to connect. The
extra connection is reserved for use by accounts that have the `SUPER'
privilege. By granting the `SUPER' privilege to administrators and not
to normal users (who should not need it), an administrator can connect
to the server and use `SHOW PROCESSLIST' to diagnose problems even if
the maximum number of unprivileged clients are connected. `SHOW
PROCESSLIST' SHOW PROCESSLIST.
The maximum number of connections MySQL can support depends on the
quality of the thread library on a given platform. Linux or Solaris
should be able to support 500-1000 simultaneous connections, depending
on how much RAM you have and what your clients are doing. Static Linux
binaries provided by MySQL AB can support up to 4000 connections.
