1. Any process, including the kernel can only allocate up to 4 GB of
memory on a 32-bit system (since a 32-bit integer can only hold that
2. The kernel is further constrained so the user programs can get enough
3. Kernel structures for tracking and using memory are also stored in
kernel memory. 24 GB of memory with PAE probably "eats up" a lot of
those. I think you'll need to increase kmem_size (see
