IME, that is not a good way to do it. Use a connection pool.

My guess would be that you have a bug in your application which is not 
always closing the connection so eventually you exceed max_connections. 
You should always close the connection in a finally{} block so that is 
guaranteed that it will be closed regardless of any earlier exceptions 
which are thrown.
