*sigh* - As soon as I turned my back to the serve console it also happened again on one of our nodes. That was 25 hours after I started the system. Usually I see these warnings a few minutes after the start, but the have been cases in the past where it took longer. So I'm not sure if the improvement is due to the patch. Josef: I was still running the patch you sent me, but there was no message from the printk's you added.
