Sounds very similar. Our servers are all identical (except for RAM).
What's unusual is that the machines we *expect* to fail sooner - don't (not even an oops). Those are very busy cache servers (several of them in a sibling cluster) which do a lot of swapping. The machines which *do* fail (or oops without any further catastrophe) are typically web/mail hosting servers (reasonably busy with about 25% swap being used). Increasing swap did not help on 2.4.5. We're still waiting for something to happen on 2.4.6 (ie, oops already appeared - waiting for meltdown, which, hopefully, will not occur). We used to auto-reboot every morning at 2am or something to keep things stable - which I *hate* because I remember having a 2.0.35/6 workstation that had an uptime of 6 months a couple of years ago. God, I loved that box.
