EGLImageKHR destruction

Using OMAP SDK 4.05.00-03 on DM3730, I notice that multiple eglCreateImageKHR/eglDestroyImageKHR (type EGL_NATIVE_PIXMAP_KHR) leads to memory leak.

And after 36 eglCreateImageKHR/eglDestroyImageKHR, eglCreateImageKHR return an error 0x300c (EGL_BAD_PARAMETER).

It looks as if eglDestroyImageKHR does not do any desallocation.

Here below the loop I tested:

for (i=0; i< NB_REPEAT; i++) {

mDrawable = 0;
  mDrawable = XCreatePixmap(x11Display, x11Window,
                         disp_w, disp_h,
                         depth);
  if (!mDrawable)
        printf("XCreatePixmap failed!\n");
  else        
        printf("loop %d drawable = %d\n",i,mDrawable);
 
  XSync(x11Display, False);
 
  //create an KHR image
  khrImage = 0;
  khrImage = peglCreateImageKHR(dpy,
                        EGL_NO_CONTEXT,
                        EGL_NATIVE_PIXMAP_KHR,
                        mDrawable,  
                        NULL);
   
  if((!khrImage) || (err = eglGetError()) != EGL_SUCCESS){
    printf("Error after peglCreateImageKHR!, error = %x\n", err);
  } else {
    printf("peglCreateImageKHR Success! \n");
  }

    XFreePixmap (x11Display, mDrawable);
    XSync(x11Display, False);

    peglDestroyImageKHR(dpy, khrImage);

  if((err = eglGetError()) != EGL_SUCCESS){
    printf("Error after peglDestroyImageKHR!, error = %x\n", err);
  } else {
    printf("peglDestroyImageKHR Success! \n");
  }        
} 

Why is the virtual memory size of the process increasing during this loop ? It isn't if no EGLImageKHR is created but only the pixmaps.

Why does eglCreateImageKHR fail (with error 0x300c) after 36 iterations ?

Thank you for your answers.
