Centos – Does segfaults mean bad memory

This is a brand new server with a new install and fresh compile of Apache/PHP with nothing crazy. Just a WordPress site hosted and I get the following.

Could this just mean bad RAM? If so how can I test it without taking the box down.

I have noticed some weird memory issues with PHP despite making the php.ini settings unlimited.
