Hi, Not being deeply familiar with the oom-killer heuristics, I could not offer reasoning why 'mate' is killed. These heuristics by default kill the most memory hogging processes in theory and the consequences of this on other processes I cannot comment on. There is one setting you may wish look at and consider. Reading: https://docs.kernel.org/admin-guide/sysctl/vm.html I see the following: https://docs.kernel.org/admin-guide/sysctl/vm.html?highlight=laptop#oom-kill-allocating-task Setting this to '1' may trigger a strategy that does not put 'mate' in the firing line as it changes the target for killing to the process call that triggers the out of memory condition. I am sure if my reading of this setting is wrong, someone will correct. This would be done of course at your own risk after doing the research yourself.
