You made me remember a extremely interesting article about Guild Wars team... they were annoyed with the amount of weird bug reports, and one of their programmers found out how to make the game self-analyze its data, and find if it was RAM hardware issue, he found out that about 1% of all their players had computers with faulty RAM, and a good amount of bug reports came from these computers, and that this program saved them a lot of money (since now they didn't needed to make devs chase "ghost" bugs, only actually real bugs).

I had bad RAM on my primary Linux desktop some ~six years ago and it caused an endless series of problems, data corruption, and hard reboots every few months. It happened so infrequently that I never quite tracked it down, but I'd copied hundreds of gigabytes of data between computers over my LAN and lots of random files still have some corrupted bits in them to this day from that.

I finally got serious about tracking down the issue, ran memtest, and sure enough, it discovered a faulty DIMM pretty quickly. I yanked it out and the problems immediately went away.
