Could you please describe your envirenment more precisely ?
I would expect at least a copy of your kernel configuration file or do
you still run a GENERIC kernel ?
Maybe you have to increase things like maxusers variable or NMBCLUSTERS.
In the kernel sources I found:
vm/vm_kern.c around line 288:
* Locate sufficient space in the map. This will give us the
final
* virtual address for the new memory, and thus will tell us the
* offset within the kernel map.
*/
vm_map_lock(map);
if (vm_map_findspace(map, vm_map_min(map), size, &addr)) {
vm_map_unlock(map);
if (map == mb_map) {
mb_map_full = TRUE;
printf("Out of mbuf clusters - adjust
NMBCLUSTERS or inc
rease maxusers!\n");
return (0);
}
if (waitflag == M_WAITOK)
panic("kmem_malloc(%d): kmem_map too small: %d
total all
ocated",
size, map->size);
return (0);
}
Since you have an enormous amount of main memory perhaps some kernel
settings
badly need finetuning. Am not sure but perhaps some kernel parameters
are adjusted
by memory size and some not, so that there is a demand of increasing
some values
to fit the others ? Just a vague guess ....

What gives you 90% more speed, for example, in kernel compilation ?
