CMEM, segmentation fault, CMEM alloc issues

Hi,

  I have a cmem error when I try to alloc 6782976 bytes with the OSA_cmemAlloc (the function is shown below, alignment is 32). I get the following error:

CMEM Error: allocHeap: ioctl CMEM_IOCALLOCHEAP failed: -1                      
ERROR  (mcvip/src/capture_tsk.c|CAPTURE_tskCreate|63): OSA_cmemAlloc()        
ERROR  (vcapture.c|UI_sysStart|150): CAPTURE_create()  

It seems to me I should have enough space to alloc my buffer. Someone has some idea of the possible cause of the issue. In the previous days I always had "segmentation fault" errors.

This is the cmem message when I load the module:

CMEMK module: built on Mar 17 2010 at 16:12:26

Here the alloc function.

Uint8 *OSA_cmemAlloc(Uint32 size, Uint32 alignment)
{
  CMEM_AllocParams  prm;
  Uint8 *virtAddr;
 
  prm.type = CMEM_HEAP;
  prm.flags = CMEM_NONCACHED;
  prm.alignment = alignment;
 
  virtAddr = (Uint8*)CMEM_alloc(size, &prm);
 
  #ifdef OSA_DEBUG_CMEM 
  OSA_printf(" OSA_CMEM: %08x %d bytes\n", (Uint32)virtAddr, size );   
  #endif
     
  return virtAddr;
}

Thank you for your support.
