DATA-BG Died Error

[bhavna]

I recently observed the following error in our system (WINCCOA 3.11.1 Platform: Windows 2008 R2 32 bit):


WCCILdata (0), 2016.01.09 17:43:09.437, SYS, WARNING, 33, General error in Data Manager, Data-BG died, please restart WinCC OA

This is for the first time in almost 10 years of operation. can anybody explain the reason behind the same.


Best regards,

Hello,

why this log-message is written cannot be seen without more detailed information. Maybe something wrong before this log message is written and the message is only a consecutive fault.
To get rid of this problem you can restart this system. Maybe the problem can also be solved by executing a online backup. During this process the databg manager is stopped and will be restarted automatically.

Thank you for the reply.

The project was restarted and all is running well. There were many messages of DP does not exist from one of the API managers. Can this cause the problem or the error will be ignored after sometime?

Hello,

an error that datapoints are missing reported by an API manager will have no effect on the functionality of the DataBg manager.
