Technical Background

When the uploaded file is corrupted in a certain way that does not trigger the archive exception, Argent AT Engine can be caught in access violation but does not label the file as bad format

As a result, the uploaded file is not discarded, and being processed over and over

The Engine process can eventually stall because of that

For customer cannot upgrade immediately, he can identify the culprit file from the Service Log, and manually remove it from UPLOAD folder and restart the service
