the class CacheServerMaxConnectionsJUnitTest method testMaxCnxLimit.

   * This test performs the following:<br>
   * 1)create server<br>
   * 2)initialize proxy object and create region for client<br>
   * 3)perform a PUT on client by acquiring Connection through proxy<br>
   * 4)stop server monitor threads in client to ensure that server treats this as dead client <br>
   * 5)wait for some time to allow server to clean up the dead client artifacts<br>
   * 6)again perform a PUT on client through same Connection and verify after the put that the
   * Connection object used was new one.
