I build all my systems with the following in make.conf:
CFLAGS= -O -mpentium -pipe -g -DKVA_PAGES=512
COPTFLAGS= -O -mpentium -pipe -DKVA_PAGES=512
and the following in my kernel config file:
options VM_KMEM_SIZE="(400*1024*1024)"
options VM_KMEM_SIZE_MAX="(400*1024*1024)"
I don't know if that will correct your problem, but the above was after
having oddles of problems with 4GB servers and *alot* of processes running
...
