This is kind of a stupid thing, but it had me stuck all morning so I thought I would share.

I currently do all of my coldfusion dev work on my OS X laptop. The CFMX7 install for apache is very nice . When I was working on one of our applications this morning I would run a few pages and then CF would return blank pages. So I would restart it and try again to no avail. I went into my CF admin settings for the JVM and noticed that my -XX:MaxPermSize was smaller than my Minimum JVM Heap Size. I set them to the same value and the problem went away. Simple fix but very frustrating.
