Because this program is very well behaved and doesn't crash if its allocations fail, so it will just stay there having claimed almost every byte.

un-fixed :( re:tech support request 

dang, the LSP edition does not appreciate running in a cgroup, huh?

re-fixed! re:tech support request 

okay, `systemd-run --user --slice=lean.slice -tPdqG --wait lean --server $file` seems to work!

Mastodon is a server for a federated social network: everyone can run a server if they want to, including me. So this is a Mastodon server for me (Vierkantor) and my friends.
