Hi, This seems to be a common complaint that the upgrade from 20.02 to 22.04 causes the OOM killer to become more active. The consensus is that 22.04 uses more memory. So you have three options. Reduce the memory usage on the box by running less, add more memory or increase your swap partition size. Increasing the swap partition size seems the easiest, see link for details https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-22-04.
I would not recommend tuning the OOM killer, it looks complicated and there is nothing worse than finding your linux box has run out of memory and become totally unresponsive. Regards, Francis.
