I have, at this point, closed the issue on our end:

https://gitlab.torproject.org/tpo/tpa/team/-/issues/41957

We've gone from 20-40 OOMs/week (multiple daily) to ~3 per week, so
Xapian has definitely improved the situation.

I don't think this bug report should be closed though: we still have a
memory leak issue. I don't think it's reasonable for mailman to take
16GB of RAM for such small setups. Xapian is also using an unreasonable
amount of disk space.

But for all intents and purposes, this is as much effort I can dedicate
to this. Hopefully, when we upgrade to trixie, we can run a profiler on
this.

Feel free to remind me of that in a year.

Otherwise happy to provide more info as needed of course.

Cheers!
