Again, sorry running short on time- I will try to post the specific tweaks that seemed to help without recompiling anything. The tweaks simply increased the # of file descriptors. I think by default the # of file descriptors is set to 300 or something really low. You need 1-3 file descriptors for each database open and of course you need it for the socket connections. Also the number of processes
Yes we saw really wierd db corrupting in a non-tuned environment. This is maily because we pushed Domino to several thousand users and the server ran out of resources b/c Linux wouldn't gwe it more things like file descriptors or sockets. At that point it panic-ed (freezing sockets) and we had to kill it. As soon as we tuned the sytem it ran extremely well at high load.
Well we ran raid 1+0 which gave us great performance and data protection. However this was hardware raid not software raid.
Here's a link to the Red Hat NotesBench report that we published:

Hopefully this helps
