Alexander, please note that if a kernel process name contains "swap" as a substring, it does not immediately mean that this process exclusively does process memory swap-in/swap-out. kswapd is a kernel process name for an important piece of memory management subsystem: it frees pages by flushing them to disk or discarding when the system is low on memory, saving you the trouble of OOMs. This includes both buffer cache and process memory; however, disk buffers are freed first.
Generally that means that on a system with disabled swap you _will_ see high cpu% in kswapd when you have almost no memory and buffers have not been synced to disk yet. This is not a bug (but you should consider installng more memory or having a stricter sync policy). However, this discussion is very off topic, since this bug is not an intended behavior. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1518457/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
