For load balancing, you can take a look at: http://www.stanford.edu/~riepel/lbnamed/ I have built several firewalls with FreeBSD and planning for failure is more an issue of planning for hardware failure, as these machines just do not crash. I do set up mirroring with ccd (details on what I learned about ccd are at http://www.i-pi.com/~ingham/ccd.html) to deal with the possibility of a disk failure. I have heard that there is a new mirroring facility in 3.x, but my firewall machines are all running 2.2.x. The biggest problem I have had is on a mail server with procmail as a local delivery agent. Procmail wants to have the whole message in memory at once, and people at one of my sites have no concept of file size or transmission time (over 56KB lines), so emailing 50MB documents is a somewhat common event. With a 16MB P120, swap space is a requirement. I added an old 400MB disk as swap space and solved the problem.
