Humm, all I can say is that its happened on 3 different boxes here, with 2 different amd cpu's, both of which get a days running of memtest86 occasionally. Really, I'd love to pin point this better, but its a lot like watching paint dry, boreing until it actually does it. gzip doesn't do it, bzip2 does it just often enough for you to forget, until it happens again.... >But again, even if there is a problem with bzip2, the solution is to > fix the bug in bzip2, not to stop using it.
