You should probably cross-post this to tech-kern, I really think this is
a kernel problem.=20

I'm not good at reading kernel debugger output, but can you find out if
the kernel really doesn't have any more memory, or if kmem_map has just
run out of mapped memory? (shouldn't it swap for more..?)

On the topic of swap? Got any? :P
