Apache DBCP Connection Pool Issue

I'm using this Apache DBCP for Connection Pool purpose. One thing I notice is that, every time there's a network failure in between my application and the database (Sql Server), yes it will generate Socket Write Failure/Error exception, and subsequent few calls would somehow cause the  getConnection() of BasicDataSource to freeze. 

I troubleshooted this by monitoring the Processes in the Activity Monitor in Sql Server. I saw there's always a Connection created each time I fired a request. That Connection would just stay, I think my application was using this particular Connection for multiple firing of requests. If I killed this particular Connection then fire a few more times, then I managed to reproduce the issue where the getConnection() was giving no response. 

After a lot of trial and error, finally I found the resolution - maxIdle of the BasicDataSource. The default maxIdle for BasicDataSource is 8, therefore I just need to set maxIdle as zero. This time, although I fired many many times , I did not see any Connection stays in the Process of Activity Monitor anymore! No more Connection Pool freeze!
