title: java.net.BindException: Address already in use: JVM_Bind <null>:80
body: <p>I am getting binding exception while starting the Tomcat server. 
  I tried to kill the process that which is using '80' as couple of processes are using it.</p>
  
  <p>Getting error, while killing process id is '0':</p>
  
  <blockquote>
    <p>ERROR: The process with PID 0 could not be terminated. Reason: This is
    critical system process. Taskkill cannot end this process.</p>
  </blockquote>
