I have seen several cases where a process slowly consumed more and more memory, but apparently always had a small working set, so it eventually consumed all the swap space and the OOM killer killed it (sometimes it killed other processes first, though). The machine was so usable during this, that I did not notice that anything was amiss until some process was missing. IIRC one of these cases happened on a machine with 24GB RAM and 48GB swap; there it took several days until the swap space was exhausted.
