Comment 2 for bug 1991163

Is it really the mailman3-web service that's using too much memory on these units?

What I've found is that usually it's the regular daily/weekly/monthly update jobs consuming most of the memory.

Sure, doesn't hurt to add these limits in place. FWIW, this was recently bumped from 1G to 4G so we should take that into consideration when adding these limits. Perhaps make it tunable via juju charm config options.
