MySQL max_user_connections ERROR :S

Question

I use PHP and MySQL. Sometimes is this:

Failed to connect to MySQL: User 'username' has exceeded the 'max_user_connections' resource (current value: 20)

Does it depend on Users on Server?

Answer 1

DB works in client-server model. All server has a pool and each pool can accommodate only certain number of connections from client at a time (predetermined by adminstrator). For example, if server connection pool is set to value 10,then only 10 client can connect. If it exceeds, there will be a runtime exception max_user_connections
