Xormon 1.8.1 - Database system in recovery mode

I've built out Xormon 1.8.1 on a Linux Debian 12 VM in VMware. All works fine for a day or so but then every 1-2 days i will try to load the URL and get the following error from the URL;

{
  "statusCode": 500,
  "message": "the database system is in recovery mode"
}

I can ssh to the VM fine and i can run ./xormon.sh stop everything stops but when I try to stop i get the following error and asked to change the password for the DB which fails.

ERROR: Database connection denied. Used credentials:

DB_HOST=127.0.0.1

DB_PORT=5432

DB_USERNAME=postgres

DB_DATABASE=postgres

error: the database system is in recovery mode
