How to kill sleeping processes (5 replies)

Hi,
I am developing a small application in c# using MySQL as database. I am opening dataabse connection and closing it after executing the query. I am using the 'using' statement and also try-catch-finally statements. Still the connection is going into sleep mode and soon it shows 'too namy connections' and application hangs. Could you please help me to solve this issue? How if I open a dbconnection in the beginning and closing it on exiting the application?

Thanks in advance
Jo
