Either you have an active page on the inactive list, or your hardware has

and should be pretty unlikely if it is a random error.

Thanks, I thought I had run memtest86 long enough when I bought the
system, but now it found one stuck bit almost immediately.

No problem. Thanks anyway for testing and reporting.
