By "empty page" I assume you mean a completely white/empty page that you get when the MediaWiki crashes/breaks? You should get an entry in the Apache error log (different from the access log) when this happens. If you aren't you may wish to check the "error_reporting" in php.ini to ensure it is set to an appropriate level. I have mine set at E_ALL which can result in large logs over time but it does catch a variety of minor warnings which are sometimes useful in diagnosing other related problems. If you change this setting make sure you restart Apache to apply the settings.
