Title:
kswapd0 100% cpu usage
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After the running the latest ubuntu for at least 2 weeks, I've noticed that kswapd0 started using 100% CPU on one of my cores.
However, I have enough of RAM and not using swap (Swap: 11876344k total, 62336k used).
The only thing I can do to remove the problem is reboot the system.
I'm using Ubuntu 10.04.1 LTS server version without any kernel modifications.
