每当我的 Ubuntu 系统接近内存耗尽时，它总是会崩溃并重置用户登录。
我检查了日志并发现了以下两条消息：
oom_reaper: reaped process 2558094 (brave), now anon-rss:180kB, file-rss:636kB, shmem- systemd-journald[354]: /dev/kmsg buffer overrun, some messages lost.
[email protected]: A process of this unit has been killed by the OOM killer.
oom_reaper 仅记录了 brave 的终止，但接下来的日志显示 gnome shell 也已终止，这可能会导致完全重置。
Brave 可能是罪魁祸首吗？还是我的看法不正确。
编辑：我似乎无法通过打开 100 多个选项卡来重现崩溃，完整的调用跟踪：
