Nice hint ! Thanks!
However, i've got no log daemon at all right now, and the only logs left are lastlog, X log, dmesg and consolekit. Of these, as i believe, only dmesg could potentially be flooded; but IIRR the kernel cuts repetitions (which occur regularly with flakey hardware) automaticly. At least i saw something like 'last message repeated xyz times' in the past.
It's actually an interesting question how the system behaves in the worst crisis (and with no swap) - it makes me think to trigger this purposely some day :)
