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.
