Why is systemd-journal taking up 110 MB? [SOLVED]

% ps -A --sort -rss -o comm,pmem,rss | head -n 20
COMMAND         %MEM   RSS
systemd-journal  2.8 109284
Xorg.bin         1.2 46268

For me, systemd-journal is taking up 2x the memory as Xorg is... I did not modify anything but that just seems wrong.  Any advice?

Not even in my top 20 list.  Something is wrong with your setup I suspect.

Re: Why is systemd-journal taking up 110 MB? [SOLVED]

$ ps -C systemd-journal -o comm,pmem,rss
COMMAND         %MEM   RSS
systemd-journal  0.0  3372

I limited the size of the journal:

$ grep -v "#"  /etc/systemd/journald.conf

[Journal]
SystemMaxUse=50M
SystemMaxFileSize=10M

I'm using ext4.


Check the logs, systemd's journal.

There's also

$ journalctl --disk-usage

For me It took more than 1 GB once. big_smile

Coredumps can also grow very fast, but they can also be limited in

/etc/systemd/coredump.conf

OP isn't asking about disk usage, but memory usage. They may be linked, but that's just a guess on my part.

Looks like limiting the maxsize also limits it in memory. Thank you for that suggestion.
