APPLICATION FAILED TO START

***************************

Description:

The Tomcat connector configured to listen on port 3000 failed to start. The port may already be in use or the connector may be misconfigured.

Fixation: 

First, find out which PID is using the port 3000. Then kill the process id.

C:\Users\drakula>netstat -ano | find "3000"

  TCP    0.0.0.0:3000           0.0.0.0:0              LISTENING       8464

  TCP    [::]:3000              [::]:0                 LISTENING       8464

C:\Users\drakula>TASKKILL /PID 8464 /F

SUCCESS: The process with PID 8464 has been terminated.

Windows Kill Process By Port Number

If you need to kill a process manually on Windows its actually pretty easy. First fire up a command prompt and type the following command.

netstat -a -o -n

To kill the process we need to find the PID of the process in question. I just run down the list by port until I find port 8080 and here you will see the process id was 28344.

Finally with the PID we can run the following command to kill the process

taskkill /F /PID 28344

Specific Port Killing

Open command prompt and run the following commands

 C:\Users\username>netstat -o -n -a | findstr 0.0:3000
   TCP    0.0.0.0:3000      0.0.0.0:0              LISTENING       3116

C:\Users\username>taskkill /F /PID 3116

, here 3116 is the process ID
