Try adding the following to your kernel config file: options "NO_SWAPPING" ...and of course re-config/build/install your kernel. I quick guess is that a traceback would show that the caller is vm_fork (calling pmap_enter). We've seen this before but haven't been able to explain how it's possible given the code involved. This is one section that was completely rewritten in -current. What are you doing on the machine? It would help if we could reproduce the problem. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
