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.
