上周，一分行管理员每天早上都要做一次Domino目录数据库的恢复操作。当时的情景是：
Names.nsf的容量〉1GB
用户登录时，收到提示：you are not authorized to use the server
Domino日志：（$User）视图错误，或 B-Tree Structure is invalid。
刚开始时，只是简单的将Names.nsf数据库从备份中恢复。但次日，故障再现。
沟通后，得知其在AIX上安装Domino时，对Data目录所在的文件系统设置了最大1GB的限额。
修改 /etc/security/limits 配置文件的default段落中fsize参数，设置 fsize=8388604 之后，重启系统，故障消失。
