有时 samba 4.1.11 会停止为客户端提供服务。每天，我都必须重新启动 smbd 才能修复此问题。Windows 客户端会提示共享设备无法访问或身份验证失败。
当他们尝试连接时，会生成以下日志：
[2014/09/17 09:37:19.739314, 2] ../source3/auth/auth.c:278(auth_check_ntlm_password)

据我所知，如果服务正常运行，则应该遵循以下几行：

任何帮助表示感谢

事实证明，默认锁定目录 (/var/lock)（由编译时使用“ --PREFIX="" ”引起）被 samba 锁定机制填满。这是一个 5MB 的 tmpfs，而通常的锁定大小为 3MB 或更大。
我建议将默认目录更改为未使用的路径。例如：
lock directory = /var/samba
