我的FreeNAS服务器上开启了Netatalk接受客户端的AFP连接。有些时候，当客户电脑打开某个特定目录时，Finder会失去响应。此时在NAS的系统日志里有大量错误消息，类似于

最近用samba4搭了一个AD，但是在FreeNAS 9.1下始终无法加入Active Directory，一启动这个服务就自动停止……
将FreeNAS 9.1升级到Beta版，甚至于Nightly版(FreeNAS-9.2.1-RC-5ccac93-x64)都无效。但是，在Nightly版本中，Active Directory的设定中多出了一项 Verbose Log 。启动后可以看到更多的Log信息。根据Log，可以看到，FreeNAS在执行到

ActiveDirectory: AD_status_domain: net -k ads status samba.whitebearhome.com

提示 Not Okay。但是我抢在FreeNAS离开域前手动在控制台执行这一句命令，结果返回是正确的。Google了一下，找到了文章。但是在FreeNAS的Nightly版中的rc.freenas文件里已经没有超时设定了。我尝试在Active Directory设定里提供的超时选项中更改，但是却没有效果。
于是，继续根据日志，发现FreeNAS是读取保存在

ActiveDirectory: AD_init: config exists, loading values from /etc/directoryservice/ActiveDirectory/config

中的配置信息的。于是手动编辑这个文件，将超时改为60，问题解决。
