Yes On my server cache memory also increases some kbs in each 15 minutes
For eg:- if free memory decreases 600 kb then cache memory increases only 100kb
Please tell what is the reason why cache increases
and any kernel tuning required for this problem.

Linux Kernels 2.6.16 and up provide a way to instruct the kernel to drop the page cache, inode and dentry caches on command. This tip can help free Linux memory without a reboot.
Note: This is a non-destructive operation. Dirty objects are not freeable, hence; you must run sync beforehand.

tau_track_memory_headroom
TAU_TRACK_MEMORY_HEA(3) TAU Instrumentation API TAU_TRACK_MEMORY_HEA(3)
NAME
TAU_TRACK_MEMORY_HEADROOM - Track the headroom (amount of memory for a process to grow) by periodically interrupting the program
SYNOPSIS
C/C++:
TAU_TRACK_MEMORY_HEADROOM(void);
Fortran:
TAU_TRACK_MEMORY_HEADROOM(void);
DESCRIPTION
Tracks the amount of memory available for the process before it runs out of free memory on the heap. This call sets up a signal handler
that is invoked every 10 seconds by an interrupt (this interval may be altered by using the TAU_SET_INTERRUPT_INTERVAL call). Inside the
interrupt handler, TAU evaluates how much memory it can allocate and associates it with the callstack using the TAU context events (See
TAU_REGISTER_CONTEXT_EVENT(3)). The user can vary the size of the callstack by setting the environment variable TAU_CALLPATH_DEPTH (default
is 2). This call is useful on machines like IBM BG/L where no virtual memory (or paging using the swap space) is present. The amount of
heap memory available to the program is limited by the amount of available physical memory. TAU executes a series of malloc calls with a
granularity of 1MB and determines the amount of memory available for the program to grow.
EXAMPLE
C/C++ :
TAU_TRACK_MEMORY_HEADROOM();
Fortran :
call TAU_TRACK_MEMORY_HEADROOM()
