我登录该系统的时候发生如下错误，包扩执行任何命令都会报错:

但如上的错误信息是由于预加载库文件的时候出错.可能跟你的某些OBJECTS过高有关,另外,操作系统的内核过高也可能有问题.
所以我通过如下步骤来进行解决。
[root@oss-ora /]# echo "" > /etc/ld.so.preload
[root@oss-ora /]# rm /etc/ld.so.preload
rm: remove regular file `/etc/ld.so.preload' y
如下再执行ls命令，没有问题。
[root@oss-ora /]# ls
bin dev home lib64 media mnt opt proc sbin srv tftpboot usr
boot etc lib lost+found misc net oracle root selinux sys tmp var
[root@oss-ora /]#
重新登录后再次执行ls等命令，没有问题，故障解决
