The machine crash again, now with the same error (before "kmem_map too
small" panic start to happen), follow the actual panic message:

After the reboot, the kernel running have the patch suggested by
ivoras_at_ (http://people.freebsd.org/~pjd/patches/vm_kern.c.2.patch),
but how the patch is related to "kmem_map too small", I don't think
that will be usefull with this panic.

I *really* need some solution :(

 Any ideas ?
