辅DNS提示：could not set file modification time of

solaris 10 BIND 9.4.2，看dmesg，有如下错误提示，区数据文件改为777也不行。solaris 10下named是以什么用户运行的啊？区数据文件放在了/var下叫named，named的属主和属组应该是什么啊？root或bin可以吗？

把辅助DNS的/var/named下的区数据文件都删除，只剩个db.cache，不手工建立辅的dns区数据文件，通过主DNS更新自动建立这几个区数据文件，观察了3个小时，没那个错误提示了。

named - g -u named 出错：区域传输出问题
