Because of this, there may be many open connections to the mainframe.Additionally, when you run the following command, you see that the number of connections to the TCP/IP address and the port number of the host increases continuously:netstat –ano –p TCPFor example, after you run this command, you may see the following information:TCP 65.53.233.90:4816 10.195.144.4:446 TIME_WAITTCP 65.53.233.90:4817 10.195.144.4:446 TIME_WAITTCP 65.53.233.90:4818 10.195.144.4:446 TIME_WAITTCP 65.53.233.90:4819 10.195.144.4:446 ESTABLISHEDTCP 65.53.233.90:4820 10.195.144.4:446 TIME_WAIT
