Server error: error while loading shared libraries

I’m having trouble with my database (MySQL 3.23.58). I’m getting an error, with the following being the error log display:

[Wed Aug 02 15:06:05 2006] [error] /usr/bin/php: error while loading shared libraries: libnsl.so.1: cannot open shared object file: Input/output error
[Wed Aug 02 15:06:05 2006] [error] Premature end of script headers: php-script

Looks like I need some help, as I’m unsure of what to do. Thanks in advance.
