We have upgraded the quick books and are using the qodbc server edition to retrieve the data for some custom reporting.  After upgraded to Intuit QuickBooks Enterprise Solutions 18.0, we are experiencing the issue while closing the quick books connection after retrieved the data from qodbc as shown in the attached images. After enabled the detailed login we are getting the following message while closing the connection some times that results in the issue.

"20200723.152721 D 32272 RequestProcessor End Session failed, the data file may have not been closed.'

Some times its working fine and in those scenarios the logs are returned as follows.

20200723.152652 D 32272 RequestProcessor Detaching SDK client from QB
20200723.152652 D 32272 RequestProcessor End Session finished OK.

The Detaching sdk client is not working some times and when checked with the qodbc forum, they are saying its related to the quick books error.
