Hi,


After we are getting the below error the entire project got crashed;

Only with this small part of the log message we cannot see why the project has stopped, possibly the Data Manager was stopped.

If you want to get more detailed information please get in contact with your common WinCC OA support.
For the analysis they will need the complete log files pmon.<hostname> and PVSS_II.log.
