Selected OOM dumps regarding Firefox
I had repeated Firefox crashes when loading an 1.6MB ASCII text file in Firefox
52.3.0. According to the sound of my disks, the system started paging a while
before Firefox was killed. A few seconds after Firefox stared to download (and
display) the file, the mouse cursor would not follow mouse movements, and the
whole system was quite slow, almost freezing.
Maybe the culprit is BtrFS:
systemd-coredump[12093]: Detected coredump of the journal daemon itself,
