Não consigo iniciar o glassfish no EC2

Não estou conseguindo iniciar o glassfish no ec2.

Comando que estou executando
asadmin> start-domain
There is a process already using the admin port 4848 – it probably is another instance of a GlassFish server.
Command start-domain failed.
asadmin> stop-domain
NCLS-ADMIN-00010
CLI306: Warning - The server located at /home/ec2-user/glassfish5/glassfish/domains/domain1 is not running.
Command stop-domain executed successfully.

Comando netstat antes de executar o comando (start-domain e stop-domain)

meu /etc/hosts está assim:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost6 localhost6.localdomain6

Lá no painel EC2 a porta 4848 está liberada

Alguém sabe porque isso está acontecendo?
