Did "apport-collect 937048" - but seems that failed because now an

** Tags added: apport-collected
** Description changed:
Description: Ubuntu 11.10
Release: 11.10
PC is running 24/7. Bug happened 3 times now, every few weeks.
Running on AMD64, 8 GB RAM, 8 GB swapfile (about 500MB in use).
It's always "comm: kswapd0", so it might be swap related.
