It was run a few minutes after. I accidentally got it live :) Well, I was expecting that because I have seen similar message previously in the logs. I think it is unlikely that things suddenly fall below 3% after the kernel has complained about the lack of swap space.

We will see soon... Thanks for the quick help! :g
