Hello,

We have a Postgres server that intermittently logs the following:

This has happened 3 times over the last 2 weeks now, without any indication what caused it.
The privileges of those 2 files are all in order.
When this happens, the server is no longer accessible, and we need to restart the service (pg_ctl restart).
Once restarted, Popstgres runs fine again for a couple of days.

We are running PostgreSQL 16.2 on macOS 14.3.1.

Any idea what might be causing this issue, or how to resolve it?


Best regards,

Nick Renders
