possible bug in filesystem driver

Linux newbie freaking out. I received this warning while performing a 'find': WARNING: Hard link count is wrong for ./proc/1/task: this may be a bug in your filesystem driver. Automatically turning on find's -noleaf option. Earlier results may have failed to include directories that should have been searched. Can anyone tell a poor newbie what this means and what I should do about it? (running 9.3 on a refurbished HP with a Celeron processor). T. Daniel
