Hi,

"Description

systemd-journald is a system service that collects and stores logging
data." -
https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html

Much likely systemd-journald requires that much memory, because it
collects a huge amount of logging data. If so, you need to get rid of
the issue that does cause the huge amount of data. The culprit unlikely
is journald-systemd, it most likely is an issue with something else and
journald-systemd does what it is purposed to do, collecting and writing
the logging data.

What logs do you see, if you are using journalctl?
