** Description changed: Hi, when the RAM is about to be full the kswapd0 process starts using very much CPU like 80-100%, and the system is unusable because of a severe lagging. What is interestin is that thunderbird seems to trigger this (e.g. when i shut down thunderbird everything comes ot normal, so let me know if you need to know the size of my thunderbird databases) more info on this comment https://bugs.launchpad.net/ubuntu/+source/linux/+bug/721896/comments/39 When this is happening, the free -m outout looks liek this: - total used free shared buffers cached + total used free shared buffers cached Mem: 3920 3822 97 0 0 344 -/+ buffers/cache: 3477 442 Swap: 0 0 0 - Enabling 1Gb swap seems to solve this issue but i did not manage to full - the swap, but if important i can try to do this. + WORKAROUND: Enabling 1Gb swap seems to solve this issue.
