server dies when idle

[verveguy]

After loading ~ 40,000 entities across two namespaces, two things have started happening:

1/ React client queries have become extremely slow. These are simple direct "by id" queries with two nested links to the other namespace. (I'm working to profile this behavior.)

2/ The local instant server, running under Orbstack, dies with the following while idle overnight. (Postgres seems fine by contrast)
