[Bug 2087886] Re: MGLRU: kswapd uses 100% CPU when MGLRU is enabled and under memory pressure
This bug is awaiting verification that the linux-azure- fips/6.8.0-1034.39+fips1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-azure-fips' to 'verification-done-noble-linux-azure-fips'. If the problem still exists, change the tag 'verification-needed-noble-linux-azure-fips' to 'verification-failed-noble-linux-azure-fips'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Bug 2087886] Re: MGLRU: kswapd uses 100% CPU when MGLRU is enabled and under memory pressure
Performing verification for Oracular. I didn't have the same real-world testbed for oracular, so I just set up a lab system and enabled MGLRU and left it running stress-ng with a memory stressor for 3 days. Its still up after 3 days, and kswapd processes are at 0%, so we will call this smoke tested, and likely fixes the issue. Marking as verified for Oracular. ** Tags removed: verification-needed-oracular-linux ** Tags added: verification-done-oracular-linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2087886 Title: MGLRU: kswapd uses 100% CPU when MGLRU is enabled and under memory pressure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2087886/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Performing verification for Noble. We installed 6.8.0-51-generic to the same DPDK compute nodes running OpenStack Yoga on Jammy. We enabled MGLRU and left them running, and checked 2 days later. Things are still stable, all kswapd processes are normal at 0% CPU. Things are looking very good.
