CMEMK Error:GETPHYS:Failed to convert virtual 0x43494000 to physical.

It is appeared  when my program run for a time ,the long time is about one hour,and the short time is about ten minutes ,it is uncertain.I

I have changed the "loadmodules.sh" like this:CMEM_MODPARAMS="phys_start  = 0x87800000 phys_end = 0x88000000,pools = 20 x4096,10x131072,2x1048576,2x4194304,2x5242880,1x8294400,1x8294400".

but the problem is already exist.  and my board is TI official's  EVM-DM365,And my DVSDK version is 4.0

My program is like this:
