Mysql Sleeping connections

I have a dedicated MYSQL server(8GB) with following MYSQL configuration.

I have a dedicated MySQL server(8GB) with following configuration.

# to do so, uncomment this line:
# symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

I have 2 applications which isare connecting to different databases  (test_db1)test_db1 and (test_db2test_db2) and performsperform all kinds of operations to the respective dbs. Both applications are written in C# and closesclose the MYSQLMySQL connections from application side.

 if (Connection != null)
            {
                if (Connection.State == ConnectionState.Open)
                {
                    Connection.Close();
                    Connection = null;
                }
            }

The 2 applications were running perfect and doing their jobs perfectperfectly. We set up replication recently and (I believe after that only) now connections are sleeping for long time and I couldn't run the application perfecthave problem. I am getting an error Two many connections after a certain timeTwo many connections after a certain time and both application willapplications stop working.

show status like '%onn%';

Variable_name             Value
Aborted_connects                 4
Connections                    1818

Ssl_connect_renegotiates         0
Ssl_finished_connects        0
Threads_connected                6

I have checked different posts asked about sleeping connection issues.Majority Majority of the posts gavegave the reply likelike client side(application) is not disconnecting connection perfectcorrectly or toto reduce the value of interactive time_out and connection_time-out.Both Both solutions are not working for me.

Thanks,
