JasperServer - Erro HTTP Status 500 -

Amigos, bom dia !
Estou decorrendo com um problema desde de ontem e não consiguo achar uma solução, seguinte, temos um servidor de relatorios (ubuntu+glassfish+jasperserver) e nao sei por que motivos parou de funcionar … sempre quando que parava eu executava o script que contem esses comandos abaixos :

root@intranet:/# cat iniciar_glassfish.sh
export JAVA_HOME=/opt/jdk1.6.0_19
cd /opt/glassfish/bin
./asadmin stop-domain domain1
./asadmin start-domain domain1

e ocorre o seguinte erro:

root@intranet:/# ./iniciar_glassfish.sh
The domain (domain1) isn’t running.
Starting Domain domain1, please wait.
Default Log location is /opt/glassfish/domains/domain1/logs/server.log.
Redirecting output to /opt/glassfish/domains/domain1/logs/server.log
Domain domain1 is ready to receive client requests. Additional services are being started in background.
Domain [domain1] is running [Sun GlassFish Enterprise Server v2.1 (9.1.1) (build b60c-fcs)] with its configuration and logs at: [/opt/glassfish/domains].
Admin Console is available at [http://localhost:4848].
Use the same port [4848] for “asadmin” commands.
User web applications are available at these URLs:
[http://localhost:8080 https://localhost:8181 ].
Following web-contexts are available:
[/web1 /__wstx-services web-form-portlet / tunnel-web google-maps-portlet mail-portlet wol-portlet chat-portlet sevencogs-theme sevencogs-hook sample-php-portlet jasperserver quercus VagasEspeciais ].
Standard JMX Clients (like JConsole) can connect to JMXServiceURL:
[service:jmx:rmi:///jndi/rmi://intranet:8686/jmxrmi] for domain management purposes.
Domain listens on at least following ports for connections:
[8080 8181 4848 3700 3820 3920 8686 ].
Domain does not support application server clusters and other standalone instances.

tentei entrar no admistração do glassfish para configurar o clusters e não lembro a senha …

Alguem tem alguma solução ?

Muito obrigado …
