W3 Total Cache Plugin 0.9.2.8
Only Page Cache, Disk Enhanced is enabled.
I'm getting blank pages randomly on my site. Purging the blank page from cache fixes the issue temporarily. After reading this post, I was able to replicate the blank pages by typing in a url with no trailing slash at the end, like so: http://www.mywebsite.com/section. Not having a forward slash at the end causes the caching plugin to cache a blank (0 bytes) page. Nothing is on that page, even when I view the source code.
Any ideas to what could be causing this?
Some details about our current set up that might help determine the root cause of the issue:
WordPress is running on Windows Azure Cloud, PHP 5.3, IIS and MySQL, and distributed in two servers. As of right now the cache is created on both servers.
