As Brian already wrote, nginx currently doesn't allow sharing of
the same cache directory between several nginx instances. It
doesn't expect cache files to appear or be changed by another
nginx instance. If you share cache directory between multiple
nginx instances - weird things will happen, and problem you see is
one of them.
