Although this bug is reported on LTS 10.04, I've to report that the bug still exists in kernel 3.1 (I'm on Debian though)! Even with swap turned off, the system still hangs as soon as there is insufficient memory. Stranger thing is, in iotop, it lists kswapd0 as having the most I/O% (i.e. highest disk activity among all processes), but both the read/write are 0 B/s!
Therefore I have a request to Arkadiy, and others: can you confirm that disabling swap like Graham did will solve the problem? I have tried both 'sudo swapoff -a' and 'sudo sysctl -w vm.swappiness=0' but it persists. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/721896 Title: kswapd0 100% cpu usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/721896/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
