This error is most likely begins with a network issue of some kind that resulted in a corrupted record being stored in the database. At that point, the Microsoft database engine then locks that corrupted record so that another user appears to be using it at the same time.
To fix this error, run the Gorilla database utilities “Database Fixer” and “Database Compactor”.
In almost all cases, this will correct the problem. Use the instructions on the knowledgebase article How to use the Database Analyzer and Database Fixer and How to Compact the Gorilla 4.x Database for information on how to run these utilities.
Sometimes, though, it may not be possible to run those utilities because of the nature of the locked record. In that event, perform the following steps.
Please note: these steps, while easy to follow, do require a working knowledge of file management in Windows.
At this point, Gorilla should function as normal and the error should be gone.
