There is a lot in that log file, but this message is describes why a new Tomcat instance didn't get started:
Port 8080 required by Tomcat v8.5 Server at localhost is already in use.
The server may already be running in another process, or a system process may be using the port.
To start this server you will need to stop the other process or change the port number(s).
