The SE reports an unhandled exception when closed while an evacuation to the Data Store is running

Summary

The Service Engine reports an unhandled exception while evacuating data  to Data Storage. This has been fixed. 

Description

The Service Engine reports an unhandled exception if data is being evacuated to Data Storage while the Service Gateway (aka Service Grid Gateway or IIoT Gateway) is closed.  This happens with large archives that take longer to evacuate to Data Storage. This error can occur when stopping the Service Engine, when reloading or when switching between server and standby.

The reason was that the component responsible for transferring the data to the Data Storage was already cleaned up while a write operation was still in progress.

This error has been fixed. The trigger for a shutdown now has the following effect:

  • No further operations are started.
  • The cleanup mechanism waits until all pending operations have been completed.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 12 or higher.
