Whats wrong with that?
The real question is "am I swapping??"
lsps - a will give you that information...
It leaves you to find out what the resource is used for... On system like AIX unused RAM is something intolerable so you leave it for a certatin time and the system will happily find some use like filesystem cache etc... and of course should be able to give that resource back if claimed by an application.. or new process....

shmget(2) System Calls Manual shmget(2)
Name
shmget - get shared memory segment
Syntax
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>
int shmget (key, size, shmflg)
key_t key;
int size, shmflg;
Description
The system call returns the shared memory identifier associated with key.
A shared memory identifier and associated data structure and shared memory segment of size size bytes are created for key, if one of the
following is true:
The key is equal to IPC_PRIVATE. For further information, see
The key does not already have a shared memory identifier associated with it, and (shmflg & IPC_CREAT ) is true.
Upon creation, the data structure associated with the new shared memory identifier is initialized as follows:
The and are set equal to the effective user ID and effective group ID of the calling process.
The low-order nine bits of are set equal to the low-order nine bits of shmflg. The is set equal to the value of size.
The and are set equal to zero (0). The shm_ctime is set equal to the current time.
Return Values
Upon successful completion, a non-negative integer, namely, a shared memory identifier is returned. Otherwise, a value of -1 is returned
and errno is set to indicated the error.
Diagnostics
The system call fails if any of the following is true:
[EINVAL] The size is less than the system-imposed minimum or greater than the system-imposed maximum.
[EACCES] A shared memory identifier exists for key, but operations permission, as specified by the low-order nine bits of shmflg,
would not be granted. For further information, see
[EINVAL] A shared memory identifier exists for key, but the size of the segment associated with it is less than size and size is not
equal to zero.
[ENOENT] A shared memory identifier does not exist for key, and (shmflg & IPC_CREAT ) is false.
[ENOSPC] A shared memory identifier is to be created, but the system-imposed limit on the maximum number of allowed shared memory
identifiers would be exceeded.
[ENOMEM] A shared memory identifier and the associated shared memory segment are to be created, but the amount of available physical
memory is not sufficient to fill the request.
[EEXIST] A shared memory identifier exists for key, but ((shmflg & IPC_CREAT ) and (shmflg & IPC_EXCL )) is true.
