There is no debugging enabled on site and there is nothing we can do now
to enable it and it is happening in only one site. But from whatever
logs I have, it is failing in calloc. 

I am not requesting help in resolving the issue with application (I will
be able to debug that), but only need help in understanding the memory
fragmentation part. ( I gave details of original problem so that I can
explain what I am trying to understand and why).
