Understanding memory fragmentation in Linux kernel

[Amit Agarwal]

Hi All, 

I am trying to understand memory fragmentation and how to understand
and/or analyze the same. 

Is there some detailed documentation on pagetypeinfo and buddyinfo files
present in the proc directory? Am I looking at right files to understand
if the memory is fragmented. 

Problem Description: 

One of the applications does a few 200-300Mb calloc's during start-up.
On one of the production servers, the application does not start up
although there should be enough RAM available for application to start.
I am suspecting that this is because of fragmentation and would like to
confirm the same.
