During my traineeship we had an PowerEdge 2650 (Dual Xeon with FreeBSD 5.1 at that time). The machine had quite high loads (8.00 - 11.00, which was 24/7), but it kept working most times. Sometimes after a few days or weeks it resulted in a panic. My mentor (who was the Unix specialist) said that it was probably been caused by the RAID controller as well. It was a PERC2/DC or PERC3/DC, not really sure. I think it's the latter. Anyway, when 5.2 came out, my mentor immediately upgraded to 5.2, and the machine became rock solid, even with very high loads. It was a monitoring machine, which collected over 1600 SMNP requests from every server, so I'm not really sure if that produces an high disk I/O or not. Perhaps the story is not interesting, but I felt like sharing that.
