Memory Issue
I could not find what is consuming the memory, generated DSET reports and NO hardware wise memory issue. 64 GB RAM on a server yet all I could see is a very limited memory available. I am not sure if I am reading this correct or not. I have used free -t -m and cat /proc/meminfo (results below)

- No users on this server yet
-One instance of an application running its owner ID is app_1

_nc_freeall

curs_memleaks(3X)														 curs_memleaks(3X)

NAME

       _nc_freeall _nc_free_and_exit - curses memory-leak checking

SYNOPSIS

       #include <curses.h>

       void _nc_freeall(void);
       void _nc_free_and_exit(int);

DESCRIPTION

       These  functions  are used to simplify analysis of memory leaks in the ncurses library.	They are normally not available; they must be con-
       figured into the library at build time using the --disable-leaks option.  That compiles-in code that frees memory that normally	would  not
       be freed.

       Any implementation of curses must not free the memory associated with a screen, since (even after calling endwin), it must be available for
       use in the next call to refresh.  There are also chunks of memory held for performance reasons.	That makes it hard to analyze  curses  ap-
       plications  for memory leaks.  To work around this, one can build a debugging version of the ncurses library which frees those chunks which
       it can, and provides these functions to free all of the memory allocated by the ncurses library.

       The _nc_free_and_exit function is the preferred one since some of the memory which is freed may be required for the application to continue
       running.  Its parameter is the code to pass to the exit routine.

RETURN VALUE

       These functions do not return a value.

PORTABILITY

       These functions are not part of the XSI interface.
