--- Blender version with error, and version that worked ---
problems from version 2.64 to 2.66
--- Short description of error ---
Rendering a scene the z value sometimes renders and sometimes doesn't. I've tried restoring factory settings and using a default cube with 2.64 to 2.66, and a default scene.
--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
Render scene, z value should be all white (or black according to the node set up). Nodes are set up for: SSS Rendering with Nodes.
Or start from default scene

I'm not sure what exact issue here?
Z-pass indeed would be white in your setup because all Z-values are obviously larger than 1. You could investigate numbers by using alt-LMB on compositor backdrop or place Normalize node between Z pass and viewer. This would make Z pass easy for visual investigation.

In Blender, the Z values are in world coordinates. distance from camera.
You clamp the z values on -1 to 3, while the rock is on 5 units away from the camera.

Thanks for the reply. After some tweaking and further searching, I've figured it out. I'll post in the forum first next time. Regards.
