I've got a Buster box (10.2) and I'm investigating some system freezes. While going through that, I think I'm not getting the OOM output in the syslog. For instance, running
tail /dev/zero which is known to trigger it, the only output I get is in the SSH shell:
tail: memory exhausted
(zsh). But nothing is mentioned in the dmesg (or journalctl fwiw) outputs, whereas on my Arch box the very same command does indeed result in a dmesg line. Why is that? Is perhaps some setting missing?
