Have you pinned down exactly *what* process is eating memory? For us
it's clearly uwsgi, so we're thinking the issue actually doesn't lie
within mailman itself, and upstream seems to think so as well.

It could be! If you could show us OOM dmesg logs, they should show which
process was actually using memory when the OOM happens, this should
inform next steps pretty well.

Alternatively, having per-process memory graphs would help too, I think.

Otherwise I'm not sure what peb needs here. :)
