This must be a 32 bit i386 kernel.

 From the vm_thread_new() error messages, your kernel virtual memory map 
is depleted.

The OS uses KVA for a physical page attribute table. Therefore the 4GB 
machine will use more KVA than a 2GB. Apparently this difference is a 
enough to cause you problems.

Either increase your KVA (KVA_PAGES setting in your kernel configuration 
file; see sys/i386/include/pmap.h look for values) or decrease your KVA 
use (memory drive?).
