Hi Rogier, My setup certainly has ECC RAM although I'm running this on a VM. So, that adds another software layer that potentially has bugs. In any case, I'm totally OK with running fsck but would like not have to manually intervene to fix problems. Any suggestions in this specific case to work around the 'required manual intervention'?

A cosmic particle may have flipped a bit in your RAM. There is not much you can do about it, except buy ECC RAM next time. Much more likely, but less likely to be believed by users is: your system simply flipped a bit. Somewhere in your system there is a path that once in a million times is not fast enough to catch the proper data, and will latch the wrong data. Result? A flipped bit. Anyway, these errors accumulate. That's why running e2fsck is still good to be doing every once in a while even on a logging filesystem like ext3 or ext4 that should be resistant to suddenly turning off the power (or crashing).
