Eu tenho uma situação aqui onde o graylog-server não se liga à porta 12900, não importa o que eu faça. Eu usei github.com/graylog2/graylog-ansible-role para instalar o rpms para graylog-server-1.1.6-1.noarch, elasticsearch-1.6.2-1.noarch, mongodb-org-server-2.6.10 -1.x86_64, nginx-1.8.0-1.el7.ngx.x86_64 em duas VMs do CentOS 7. graylog-server é iniciado, não registra nenhum erro em /var/log/graylog/server.log, mas falha ao vincular à porta 12900.

A VM que estou usando tem 4 GB de RAM e a JVM está configurada para usar 1G. Gostaria de saber se o erro de falta de memória é o resultado de iniciar muitos manipuladores de transporte multicast. Alguma idéia?
