[Kernel-packages] [Bug 1518457] Re: kswapd0 100% CPU usage
After upgrading to 4.4.0-45 from 4.4.0-21 the issue seems to have gone away. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage Status in Linux: Unknown Status in linux package in Ubuntu: Invalid Status in linux source package in Xenial: Fix Released Status in linux source package in Yakkety: Invalid Bug description: As per bug 721896 and various others: I'm on an AWS t2.micro instance (Xeon E5-2670, 991MiB of memory). Occasionally (about once a day), kswapd0 falls into a busy loop and spins on 100% CPU usage indefinitely. This can be provoked by copying/writing large files (e.g. dding a 256MB file), but it happens occasionally otherwise. System memory usage (not including buffers/caches) currently sits at 36%, which is typical[1]. Initially I had no swap space configured; I've since tried enabling a 256MB swap file, but the problem continues to occur and no swap space is used. The system can be recovered with `echo 1 > /proc/sys/vm/drop_caches`. Happy to provide further information/take further debugging actions.
