Olá!

Há pouco tempo, o servidor que mantenho passou a amitir, continuamente, a exceção abaixo:

Durante o dia, é possível utilizar o sistema com certa lentidão. Mas, após tentativa de backup dos índices do Solr4, durante a madrugada, o sistema fica inacessível, necessitando ser reiniciado.

Já aumentei os valores em todas as propriedades de timeout que encontrei, mas nada surtiu efeito. O número médio de usuários simultâneos geralmente não ultrapassa 10. Utilizamos SSL e proxy reverso com Nginx.

Se alguém tem ideia do que seja, agradeço o compartilhamento.

Boa tarde.

Só esse log não basta.

Para que possamos tentar te ajudar, por favor, compartilhe o log completo, desde o inicio do serviço ate quando o problema acontece.

Além disso, se você conseguir identificar alguma possível ação ou evento que cause o problema, seria bastante útil.
