Storage Manager error: Times out while waiting for a database connection to become available in the connection pool.

Engine running on OES2018sp3, Storage manager 5.3, Admin console  Broke from one day to the next.  Does not manage home directories.

I checked the firewall on engine server and port 3009 is open.  Also tried shutting down the firewall and still same error.

Using nsmengine-config, I try to stop the service and it hangs and fails.  I am able to start the service and it shows as running but still get the errors.

Top shows the nsmengined process running at 100%Server has 16GB memory and 13GB free.  no space issues on the system partition.
