 Description   

There are certain cases when CMAPI doesn't explicitly tell that it shuts the system down so that might cause DMLProc and potentially DDLProc to left some bits of txn so on the next cluster start there might have issues, e.g. there might be some logging messages like below or more severe issues.

Closing it b/c there I'd found no scenario to reproduce it.
