Message Queues Problem

I installed our running application on a new rp3440 machine. The application uses message queues for IPC. I used the compiler option
-D__BIGMSGQUEUE_ENABLED to have a larger message queue; but the program is unable to create the queues. I have already set the msgseg-> 8192; msgssz->64; msgmnb-> 262144 and rebuilt the kernel and re-booted the system. Is there some other parameter to be set which I have missed?
