Spell out your words.

This:

may help. Could also be a software problem triggering things, or some memory is going bad. Running memtest for a good while would be a good place to start. Also, you should call RedHat support, since you're paying for it with your RHEL subscription. If you're not paying for it, you shouldn't be using it, since you won't be able to upgrade, get patches/fixes/additional packages, etc.

I also have this issue on my CentOS 5.2 system. It usually occurs when the system is running some heavy computations for a long time and hasn't been rebooted for months!
But since that doesn't really affect anything else, I just ignore it and reboot when possible!
