Graceful failure instead of panicking in kmem_malloc

[Bharma Ji]

In FreeBSD 6_2, if kmem_malloc is unable to find space it panics. The
relevant code is in vm_kern.c
  if ((flags & M_NOWAIT) == 0)
                         panic("kmem_malloc(%ld): kmem_map too small: %ld
total allocated",
                                (long)size, (long)map->size);

Is there any way to make the system log and then gracefully shut off instead
of panicking?
