Oi, estamos executando um servidor Samba 4.6.2 com integração do Microsoft Active Directory. Depois de atualizar o CentOS 7.3 para a versão 7.4, nosso servidor Samba começou a gerar erros. Alguns usuários não podem copiar arquivos da área de trabalho para o servidor.
O Samba está falhando com os core dumps e, depois de um reinício, tudo funcionou bem por meia hora e então o Samba começou a registrar erros novamente. Mesmo depois de reiniciar o servidor, o Samba começa a gerar erros. Eu li a seção de instruções, mas isso fornece apenas etapas básicas de solução de problemas, nada a respeito de um erro tão grave quanto este.
Estamos usando o CentOS 7.4 com a versão mais recente do kernel 3.10.0-693.2.2.el7.x86_64. Nosso servidor de arquivos tem 16 GB de RAM e 4 núcleos de cpu. Eu ficaria feliz com qualquer ajuda.
Aqui está o meu arquivo de log (/ var / log / messages):

Veja minha resposta aqui: PCs com Windows sendo solicitada a senha após a atualização do CentOS 7.4 / Samba 4.6.2?
A solução foi adicionar ao smb.conf na seção Global:
ntlm auth = yes
Isso pode estar relacionado ao seu problema. Há um problema com NTLMv1 vs. NTLMv2, mencionado nas notas de versão do Samba 4.6.2.
