R help - Jun 2021 - Mediation analysis takes up all RAM, then all swap, and then RStudio/terminal suddenly closes

I am using the mediation <https://cran.r-project.org/package=mediation> 
package to run a mediation analysis.

But when I call the `mediate` function, R eats up all RAM, then it eats 
up all swap, and then RStudio suddenly closes.

The same happens if I call `Rscript` from the terminal, and the terminal 
suddenly closes.

Here is measures for RAM and swap. Notice the peaks:

I have Fedora Worstation 24.

This happens BOTH with the R 4.0.5 that uses Open BLAS provided in the 
Fedora repository, and a custom R 4.1.0 I compiled from source linked 
against Intel MKL.

It doesn't seem to happen every time, some times (rarely), the RAM stays 
constant (around 40/50%) and it works (it takes a long time through).

What is the cause of this? How can I debug?

Please read and follow the posting guide, linked below, which says:

"For questions about functions in standard packages distributed with R (see
the FAQ Add-on packages in R
<https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R>), ask
questions on R-help.
If the question relates to a *contributed package* , e.g., one downloaded
from CRAN, try contacting the package maintainer first. You can also use
find("functionname") and packageDescription("packagename")
to find this
information. *Only* send such questions to R-help or R-devel if you get no
reply or need further assistance. This applies to both requests for help
and to bug reports."

So, while you *may* get a useful response here, you should contact the
maintainer. If you have already done so, please say so.

Another possibility that may be helpful is the Fedora SIG,
https://stat.ethz.ch/mailman/listinfo/r-sig-fedora , though of course I
have no idea whether your problem is OS specific.
