monitoring

I would like to monitor the ram of two linux systems (Ubuntu and Red Hat). I realize I can run memtest86 from boot to diagnose bad ram. But are there are any solutions to monitor ram while the system is still running. I'm sort of thinking a daemon that writes and reads back from random unused memory. Anybody seen something like this before?
