This is the log entry from atop approx seven minutes before the crash, in case it helps any. It doesn't look like anything was using a lot of memory other than cache (if I'm reading it right, it reports only 21MB free RAM but the most memory-hungry process is Xorg with only 3%). Looking through the atop logs, 21MB is unusually low though.
