Step-1 : Check the Process : netstat -tulpn or netstat -tulpn | grep port_no

[Port in question – 8000]
root@core3xdockers:~/godev/src/github.com/ev2xchaincodeservice# netstat -tulpn

Step-2 : Kill this Process

root@core3xdockers:~/godev/src/github.com/ev2xchaincodeservice# kill -9 6025

Step-3 : Verify the nestat table

root@core3xdockers:~/godev/src/github.com/ev2xchaincodeservice# netstat -tulpn
