[Touch-packages] [Bug 1966381] Re: applications crash that never crashed under Ubuntu-20.04
Well funny you should say that... When I installed 22.04 on my new Dell laptop with 16G RAM, Jammy still only allocated 976MB of swap. I think you have a problem there too. So after reporting this issue and continually having OOM crashes, I created a 20G swapfile - and ever since this problem has disappeared...

[Touch-packages] [Bug 1966381] Re: applications crash that never crashed under Ubuntu-20.04
In the near term, we could consider tweaking the systemd-oomd defaults in Ubuntu. According to the commit that added systemd-oomd in Jammy [1], the current config is based on Fedora's. This includes using the default value of SwapUsedLimit=90% [2]. However, Fedora has more swap space by default: a fresh install of Fedora 35 in a VM with 4GB of memory has 4GB of swap, whereas a fresh install of Jammy in a VM with 4GB of memory has 968MB of swap. So, maybe the default SwapUsedLimit is not appropriate for Ubuntu.

[Touch-packages] [Bug 1966381] Re: applications crash that never crashed under Ubuntu-20.04
wow, looking at the systemd code (even upstream), oomd is counting pagecache as 'used' memory which is massively unfair as the kernel is responsible for pagecache use, not userspace, and it's not even accurate (from a OOM perspective) since the kernel will drop pagecache as memory pressure increases.

FYI About 6 hours ago I saw a new release of systemd-oom was released (249.11-0ubuntu2). I've upgraded the entire system and rebooted, so I'll report back if there's any change.
