Boa tarde pessoal! Tenho dois servidores que se comunicam por NFS, um tem o apache instalado e busca os arquivos do site no outro servidor, acontece que do nada a conexão NFS cai, e fica uns minutos fora e depois volta, isso acontece muito de madrugada ate de manha dai depois normaliza, agente já fez de tudo, atualizamos kernel, NFS, firmware, troquei palaca de rede, cabo. Me lembrei que li alguma vez em algum lugar que o NFS tem um limite de tranferências de arquivo, isso começou faz uns 3 meses, esse servidor ta no ar desde 2008 e sempre funcionou direitinho com essas configurações. Segue um pedaço do log:
