有时桑巴4.1.11停止为客户提供服务。 每天，我必须重新启动smbd才能解决这个问题。 Windows客户端说，共享设备无法访问或authentication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) check_ntlm_password: authentication for user [user] -> [user] -> [DOMAIN\user] succeeded [2014/09/17 09:58:41.021885, 1] ../source3/param/loadparm.c:3178(lp_do_parameter) WARNING: The "idmap uid" option is deprecated [2014/09/17 09:58:41.022305, 1] ../source3/param/loadparm.c:3178(lp_do_parameter) WARNING: The "idmap gid" option is deprecated [2014/09/17 09:58:41.022621, 2] ../source3/param/loadparm.c:3581(do_section) Processing section "[home]" [2014/09/17 09:58:41.028757, 2] ../source3/auth/auth.c:278(auth_check_ntlm_password) check_ntlm_password: authentication for user [user] -> [user] -> [DOMAIN\user] succeeded AFAIK接下来几行应遵循，如果服务正常工作：

任何帮助赞赏
事实certificate，在编译时由'–PREFIX =“”'引起的默认locking目录（/ var / lock）被sambalocking机制填满。 这是一个5MB的tmpfs，通常的锁的大小是3MB或更多。
我build议将默认目录更改为未使用的path。 例如：
lock directory = /var/samba
