Now what I should do to solve it. Thank you

Answer 1

Cause

The port Bamboo is attempting to use is already in use. This can be caused either by another application running on the port or failed shutdown of Bamboo that has left the port open.

Solution

On Windows

1. Hit Ctrl-alt-delete and look at open programs. Look for java.exe.
2. From a command window, run netstat -an. Check which ports are in use. You can identify which application is running this way, then close it from the Task Manager.

On Linux

Run: ps -aux | grep java. This will show the java processes running and their process ids. You can kill a process with the command: kill -9 <pid>
