Hi Fabian,
I am seeing a lot of SQLExceptions in the logs:
16:15:16,595 INFO [SystemPropertiesInitializer] Initialising System properties for PAM
16:15:17,706 DEBUG [SystemPropertiesInitializer] Starting failed c2o.system:service=SystemPropertiesInitializer
java.sql.SQLException: Network error IOException: Connection refused: connect
Can you make sure your SQL Server is up and your PAM server can access it.
