Comment 5 for bug 560859

Since some days this happens to me too. Is this bug not duplicate or related to bug 501715 ? At least I think it is ureadahead fault, because htop doesn't display any process consuming that much of memory.

In a Kubuntu 10.04 system with only Firefox running, the swap is now 890 MB full, in Karmic it was at most ~130 MB used. After I disactivate the swap, the system becomes very slow, and then the programs start to crash. Only restarting helps, but for about 2-3 hours.
