Dear Demetres, I googled the Ubuntu 22.04 release notes and found https://discourse.ubuntu.com/t/jammy-jellyfish-release-notes/24668 which says "We’ve enabled the userspace OOMD service and are shipping the systemd-oomd package by default on the “Ubuntu Desktop” flavour, to avoid overloaded systems and the need of the kernel’s OOM killer to kick in. The OOMD status can be checked using oomctl." Then googling "Ubuntu 22.04 oomctl" takes me e.g. to https://askubuntu.com/questions/1405021/firefox-closes-by-itself-in-ubuntu-22-04 and https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1972159 which confirms that there may be a problem in Ubuntu 22.04 with processes being killed without good reason, and some hints on how to configure your system to avoid that.
Maybe the systems-oomd package can simply be removed. Hope that helps, Kay On Tue, 29 Nov 2022 10:25:17 +0200, Demetres D.
