The consistency is the servers that lock up are fine when not using
any nfs or sshfs mounts. But the 2 servers that are fine use dc and
re network adaptors.
I am not able to setup my local bsd box until a new hd arrives next
monday and will be a day or so before I get it setup to mirror the
production conditions of the servers and I will then mount some nfs on
it to repeat the problem.
