I may confirm having similar issue.

It was happening regularly under EXWM. Memory get occupied more and
more and more until it does not go any more, swapping becomes tedious
and computer becomes non-responsive. Then I had to kill it. By using
symon-mode I could see swapping of 8 GB and more. My memory is 4 GB
plus 8 GB swap currently.

This similar condition takes place only after keeping Emacs long in
memory like maybe 5-8 hours.

After putting laptop to sleep it happens more often.

When I changed to IceWM this happened only once.
