Quando o software de varredura Tenable verifica a porta 9083, o gerenciamento remoto do PowerPath com processo habilitado para mTLS falha, eventualmente atingindo o máximo de conexões de soquete, e a conexão redefinida por mensagem de par é registrada.
Na GUI do PPMA, o status desconectado não é exibido até o próximo ciclo de consulta. Quando o ciclo de consulta é executado, o servidor eventualmente é exibido como desconectado na GUI (VERMELHO).

Esse é um problema em que o gerenciamento remoto do PowerPath para Windows 7.2.X com mTLS ativado não manipula corretamente as conexões Winsock de servidores que não são do PPMA.
A correção ocorrerá na versão futura do PowerPath for Windows, mas não há ETA no momento.
A solução temporária é reiniciar o serviço "EMC PowerPath Remote Management Component" nos serviços do Windows.
