503 Service Unavailable - Dispatcher running but no server connected!

Hi All,

We have a EP7.0 system pure Java Instance. The system is connected to BI on the backend.

Past few days the server is runing, but we get this error on the page and we had to restart the JAVA instance from the JCmon, but still it repeats.
