server admin; microblog.pub
Seems like there's some kind of memory leak in the microblog.pub code. I have to restart the server processes at least once a day to keep things running smoothly. I'm very happy overall on this new server, but this is definitely something I need to fix before I can comfortably make it my main account.
microblog.pub maintenance
Managed to (mostly) stabilise memory usage. They key change was to update some dependencies, particularly greenlet. Reusing httpx clients instead of creating a new one for each ActivityPub call also helped.
In the process I got enough confidence in the maintainability of this codebase, so I might pull the trigger and move my main over here soon.
