Having issues getting wp-cache and apc to play nice? So was mark, luckily he found the answer so I can link to him

APC (Alternative PHP Cache) is great for WordPress. It caches the
compiled WordPress PHP files and greatly speeds up subsequent loads. I
even wrote a WordPress plugin to make WordPress store its objects in
APC instead of in the default file-based object cache.

WP-Cache2 is also great for WordPress, because it caches the HTML output of WordPress for a specified period.

So if both are good, together they should be awesome, right? Well…
in theory, yes. Unfortunately, I’ve been having a heck of a time
getting them to play together. What would happen was that pages would
start showing up blank. Just a white page. Real helpful. The same thing
happened when you tried to access /wp-admin/ The only way to fix it was to delete WP-Cache2. In desperation, I removed all the error-silencing @ from WP-Cache2. Ah. It was some problem with class_exists() and APC. Apparently, APC doesn’t play well with class_exists().
