If you allow Windows to control the Pagefile size and it becomes a variable relative to need, rather like a balloon can expand, what happens when you customize the size ? This fixes the size at a value decided by yourself, albeit too much or too little.
So what happens when the system requires more Pagefile capacity than you have allowed ?
I have mine at a "fixed" size, and I do quote the word fixed because I have observed Windows black/white magic on a couple of occasions ignoring my set limit of 1024 MB and using more when it needs to. After a startup or reboot it's back to the set size of 1024 MB.

You run out of virtual memory and windows asks you to close stuff
I personally disable the page file completely as it is rare that I use even half my ram (barring firefox memory leaks from a few months ago). I've only ever run into one program that demanded a page file
I'd imagine if you set the upper limit too low that you would get the old message "Your system is running low on virtual memory".
I set all PC's to 512 min, 4096 max and have never had an issue. I have 8g ram but I still do that customised settings to any PC despite it's ram amount.
