High resolution problem

Hi,

A question addressed to any IPNC expert. I will really appreciate help in this regard because I am stuck in this problem since many days and don't get any solution. 

I am trying to get 5MP resolution from DMVA2IPNC-mt5 camera. I have reduced the linux memory to 27, but still when I l set the 5MP resolution with ./av_server.out DM368 RTSP AEWB APPRO2A 5MP MJPEG 50 MENUOFF &, I get following error: 

CMEM Error: allocHeap: Failed to mmap buffer at physical address 0x84140000

CMEM Error:     Freeing phys buffer 0x84140000

I disabled motion detection thread, but still get the same error. I then tried to disable FD thread, but it seems to be a bit difficult due to various message passing among the threads. 

Please any one tell me how can I solve this problem. I use following insmod:

insmod cmemk.ko phys_start=0x81e00000 phys_end=0x88000000 allowOverlap=1 phys_start_1=0x00001000 phys_end_1=0x00008000 pools_1=1x28672

Regards,
