I have  the following options in the kernel 

# Fix for the Memory problems
options         VM_KMEM_SIZE_SCALE="4"
options         VM_KMEM_SIZE_MAX="(1024*1024*1024)"
options         KVA_PAGES=512

It runs stable for 4 Years now. Some problem when hyperthreading is enabled, 
but without hyperthreading it's stable sofar.
