Server fails to remain started

I'm running the Traccar 4.12 Docker image in Kubernetes with this config (sanitized for security):

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'>
<properties>
  <entry key='database.driver'>org.postgresql.Driver</entry>
  <entry key='database.url'>jdbc:postgresql://<host>:5432/traccar</entry>
  <entry key='database.user'>username</entry>
  <entry key='database.password'>password</entry>
  <entry key='logger.console'>true</entry>
  <entry key='logger.level'>all</entry>
</properties>

The server is just stopping, with no noticeable reason for failure. I've checked firewalls, network paths, credentials, etc. I cannot figure out a reason the server would just stop as everything else is fine. Thoughts?

$ kubectl logs -f hurricane-server-traccar-0

Is there a reason you enabled all log levels? It actually makes it impossible to compare to what it should actually look like, so I don't think it's very useful.

I have them all enabled for debugging, I'm going to be turning the off after I find the problem. This is a net-new deployment, so there's not a "normal" log stream yet. I can't find any errors with my config or causes that would make the server shutdown. It usually shuts down about 25-35 seconds after it boots, but I can't figure out why. I thought it was the database connection but I've resolved all those errors.
