今天再安装rpm包的时候居然碰到了ERROR，如下：

ERROR: ld.so: object '/lib/libcwait.so' from /etc/ld.so.preload cannot be preloaded: ignored.
ERROR: ld.so: object '/lib/libcwait.so' from /etc/ld.so.preload cannot be preloaded: ignored.
ERROR: ld.so: object '/lib/libcwait.so' from /etc/ld.so.preload cannot be preloaded: ignored.

ERROR: ld.so: object '/lib/libcwait.so' from /etc/ld.so.preload cannot be preloaded: ignored.

环境：

redhat 5.4 x86 64bit

找了相关信息，最终解决：

echo "" > /etc/ld.so.preload
