If rebooting the machine made the (apparent) error go away, then
my guess would be a bit got flipped in RAM, the page of RAM that
held the cached copy of the page from disk. While I worked at a
large chip company, I heard of cosmic rays, alpha particles, and
such causing occasional soft errors in RAM. (That's why ECC RAM
was a primary factor in the motherboard I chose when I built my
machines.) I would suggest running memtest86 overnight to check
for something more sinister.
At last, someone who agrees with me about the essentiality of ECC.
Most of the uninformed keep spouting 'unneeded' when told to insist
on it in every machine.
