You have not provided any details about your project, your footage, effects etc. This error, while common in the olden days of AE, these days almost always only comes up when footage is damaged or effects are buggy.
A composition frame that is 16Kx16K requires a gigabyte at 8 bits per channel (bpc), so it should fit in memory at that color depth, even with the old 32-bit After Effects CS4.
Is your project color bit depth set to 8bpc, or is it set higher? At 32 bpc, that frame can't possibly fit in memory, since a 32-bit application can't address enough RAM.
BTW, this is one of the many reasons to be using 64-bit After Effects CS5 or later.
Go to your Secret preferences settings and set the render engine to purge after every frame. Get there by holding down the Shift key while clicking Preferences>General
If that doesn't help tell us everything about your project.
Many thanks to the three of you. Just got back from a video project that I've got to start editing. Let me go over your comments above and I'll get back.
I do appreciate your suggestions.
OK, here goes. Thanks for being patient.
Mylenium, No footage used. I was just testing some Digital Juice templates called Ready 2 Go for Adobe After Effects. I changed some of the text. Added no video clips, added no effects.
Todd, I set it at 8 bits to be sure. Yes, I've gotten the suggestion to go to CS6 many times. Gotta get CS6, but I can't afford it.
Rick, I'm going to go purge right now. I'll get back on that.

I found the latest CC version at less than $40 a month to be fairly affordable.
Eureka ! It worked. Thanks so much. Fantastic.

Glad I answered your question.
