Erro de implementação do Tomcat7

Eu tenho um aplicativo da web que eu posso construir e testar dentro do meu ambiente Eclipse. Ele funciona perfeitamente quando executo o aplicativo no ambiente do Eclipse. No entanto, quando eu implantei no meu servidor Tomcat7 no Ubuntu, ele relatou erros.

Eu iniciei meu Tomcat usando o seguinte comando:

sudo /etc/init.d/tomcat7 start

E, inicialmente, ele solicitou que ficasse bem na inicialização do servidor:

 * Starting Tomcat servlet engine tomcat7                                [ OK ]

Mas quando eu digitei o endereço no navegador: http://localhost:8080/RestWS , ele não respondeu, mas apenas a tela em branco. Então expirou e caiu.

Eu procurei o arquivo de log localizado em /var/log/tomcat7 , ele mostra a seguinte mensagem de erro:

Estou usando o Tomcat 7 e o JDK 7 no Ubuntu 12.04. Então, o que causou o problema? Por que o Tomcat não respondeu? Ele funcionou bem quando eu lancei no Eclipse embora.

Parece que a JVM está ficando sem memória, daí o erro:

java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space

Verifique sua configuração do Tomcat e certifique-se de que o Tomcat esteja alocando apenas a quantidade de memória adequada ao seu sistema.
