I don't know if I will have your answer, but the images of the settings you posted are to difficult to read.

The screen shots are too small - I can't read the settings.

 

You have 3 gigs of ram and a 32-bit OS. It might be having to hit the hard drive for more virtual RAM. Hard drives are a lot slower than ram chips.

 

Another thing could be the material at that particular location. A combination of light and materials might be making the render engine get really confused.

I cannot see your settings, but have you tried lowering the AntiAlias and/or Final Gather settings to see if it chugs past that point?

 

I had this happen to me once and I nudged the camera to the left slightly and it rendered fine. My issue was a really bright reflection on a material with a lot of samples.

http://en.wikipedia.org/wiki/Antialias

has some visual examples

 

Basically, AntiAliasing helps with details.

 

From my notes:

Anti-alias and Oversampling

* Renderer tab

* the antialias filter is here (Filter type)

* oversampling is the min/max

* min:4 and max:16 is a high quality setting - gets rid of aliasing

* min:4 and max:64 - very high quality setting

* Tip From Justin Hunt

90% of the time I use Min: 1 Max: 16

if there is a lot of fine detail, moire patterns or detail "melting" into each other then I do 4, 16.

For testing I start at 1/4 , 4. If I ahve time in animations then it 4 ,16 (more if needed)

You can also drop the spatual contrast so that the max samples start sooner.
