Ubuntu 10.04.1 LTS And High CPU Usage From kswapd0
I was using the recommend Paravirt kernel for this installation. I read that newer kernels had a patch for the kswapd0 high cpu issue, so I am now using the 2.6.39-linode33 kernel and I am not seeing any issues with kswapd0.
Has anyone else come across high cpu utilization for kswapd0 on their Ubuntu 10.04 installations?
Also is it advisable to run the 2.6.39-linode33 kernel on 10.04? Any recommendations appreciated.
I also have been dealing with this problem over the past few days, and for me I think it was that I had a memory leak and my linode was running out of memory. When that happened, it would just hit swap and the I/O would spike.
I don't know if I've fixed it yet, but what has helped me is running 'htop' to see what processes are taking up a lot of memory and seeing how to optimize those.
