Server is not available

The lone database I use that’s been set up to be shared, Mail Log, suddenly shows “Server is not available…” in the Server pane under Database Options. The server also does not show up in the Server Administration page.

How can I recreate / restart the server and get the shared database back to syncing with this server?

10.2.0.b30 on MacOS 10.14.6

Never mind. All of a sudden, after force quitting from a couple of other programs, it’s back. Weird.

Your server computer may have run out of memory.
