Comment 49 for bug 721896

Since Ubuntu 13.10 update, I have high cpu loads which eventually (after 5-10sec) lead to a blocked system.
Same reason: kswapd0 uses lots of CPU. Also seems mostly in conjunction with Chrome when having many open tabs. Freeing memory by closing Chrome (or another heavy app) in time before the system becomes unresponsive helps, otherwise it crashes.

Freezes / crashes of this kind never happened before 13.10. though. Maybe the new zswap feature could play a role?
