I've seen the same thing happening in random sites (mostly wikipedia) and some wikis. Might be a Google Chrome issue. I also noticed that the wiki is using at least one script that seems to use AJAX  calls  (and also API calls)  on every page load(http://tibia.wikia.com/wiki/MediaWiki:Custom_Scripts/VandalWarn.js). This could be affecting performance, and triggering these "white pages "more often.

With this in mind, I would suggest that wikia should add an additional rule to the JS review "


 * "Scripts must not have severe negative effects on reader or server performance".

While most users probaly don't know how to mess up the performance, they may run loads of javascript tools that may cause issues .
